Oh, sibling adventures are my jam! 'The Unwanteds' by Lisa McMann isn’t exactly brother-sister, but Alex and Aaron’s twin rivalry-turned-redemption arc in a magical world is packed with emotional punches. One’s artistic, the other’s a rule-follower—their clashes and eventual teamwork had me hooked. Then there’s 'Greenglass House' by Kate Milford. Milo and Meddy (disguised as siblings) solve mysteries in a smuggler’s inn, blending folklore and cozy danger. The chemistry’s more subtle, but the way they decode puzzles together feels like a warm hug.
For a wilder ride, 'The Mysterious Benedict Society' has Reynie and Kate, though not blood-related, operating like siblings—brainy, brave, and endlessly loyal. The series celebrates found family, which hits just as hard. And if you’re okay with graphic novels, 'Witch Boy' by Molly Ostertag features Aster and his sisters navigating magic and gender roles—quietly revolutionary with gorgeous art.

If you're hunting for sibling adventures with that 'Percy Jackson' vibe, let me gush about 'The Kane Chronicles' by Rick Riordan first. It's like Percy but with Egyptian mythology—super fun! Carter and Sadie Kane are this estranged brother-sister duo who reunite to battle gods and uncover family secrets. The banter between them is chef's kiss, and the way they play off each other’s strengths (Sadie’s sass vs. Carter’s cautiousness) gives major 'Annabeth-Percy' energy. Riordan’s trademark humor is there, too—expect talking crocodiles and chaotic magic.
Another gem is 'The Blackwell Pages' by K.L. Armstrong and M.A. Marr. Twins Matt and Laurie discover they’re descendants of Norse gods and get dragged into Ragnarök-level drama. The dynamic feels authentic—they argue, protect each other, and share this unspoken bond when things get wild. Bonus: Loki’s kids are side characters, and they steal every scene. For something darker, 'Lockwood & Co.' by Jonathan Stroud isn’t siblings, but Lucy and Lockwood’s found-family teamwork might scratch the itch.

You’ve gotta check out 'The Adventurers Guild' by Zack Loran Clark and Nick Eliopulos. Zed and Brock aren’t siblings, but their bond is so brotherly it counts—think reckless bravery meets sarcastic backup. The dungeon-crawling action and medieval fantasy setting make it feel like a D&D campaign gone epic.
Also, 'Serafina and the Black Cloak' by Robert Beatty pairs Serafina with her friend Braden, who bicker like siblings while unraveling creepy mansion mysteries. The Southern Gothic vibe adds a fresh twist. And don’t sleep on 'Theodosia Throckmorton'—while Theo’s adventures are solo, her brother’s occasional appearances add hilarious chaos. Siblings in books just get that mix of annoyance and unwavering support, y’know?

“Say it like you mean it, darling,” he purred, leaning in and licking my neck, “and I might stop.”
*
My mother got remarried… and cursed me in the process.
I thought moving into this mansion would be the worst part of it. I was wrong.
Because living here means living under the same roof with them.
The Varkas brothers.
Beautiful. Dangerous. Possessive.
And absolutely, devastatingly off-limits.
They call me “stepsister.”
But the way they look at me? The way they touch me?
It’s anything but brotherly.
There’s something wrong with them. Something not… human.
I can feel it in the way their eyes flash when they’re angry.
In the way their bodies burn hotter than they should.
In the way they move, like predators in the dark.
I don’t know what they are.
But I know one thing… whatever’s hunting me now, I won’t survive it.
Not if I keep letting them close.
Not if I keep letting them ruin me with their hands, their mouths, their filthy words.
I should run.
I should fight.
But the truth is… part of me doesn’t want to escape.
Because whatever they are…
I crave it.
And once they claim me, there’s no coming back.
One more thing… All three of them touch me, all three of them make me feel things, but there’s one in particular…
One…

AUTHOR’S NOTE: A fair warning before you open this book; this isn't a sweet romance kind of book. It’s dark, filled with sensual fantasies, fleshing longings, erotic musings, and lots, and lots of smut. So if this is your kind of vibe, “Welcome, princess and make sure you wear your seat belt.” But if this is not, then…
Lycan children born from Alphas often came in twins or triplets. Destined to be matched with one female throughout their reign. But it wasn’t that simple. Some Alpha siblings were willing to share. Others prepared to kill one another to keep their mate to themselves. It was no different for Jaxon and Xander.
Having already rejected three mates they are paired with a fourth, something that wasn’t heard of. The only problem was, she wasn’t a Lycan.
Blue is a wolf with no pack. She refuses to live as a wolf, and instead lives among humans. When Jaxon and Xander walk into her life, they turn it upside down. Secrets that she had kept hidden for a long time start to come to the surface, revealing Blue for what she really is.
Valeria’s plan was simple:
Endure living in the same house as her notoriously sexy stepbrothers.
Make it through the last months of high school.
Leave the Red Ridge Pack—forever.
And things were going quite well until the first thing her wolf - Hazel - screamed on her eighteenth birthday was, “Mates!”
To her horror, she looked up and saw it wasn’t just one—but all four of her stepbrothers.
Alerion, the cold and calculating leader.
Caius, the cute geek
Zane, the Casanova, who made her heart race and her head spin.
And Lysander, the quirky one who had sworn to make her life in school difficult
Each of them is determined to stake their claim, but Valeria has no interest in being part of their game. With her stepfather pressuring her into an arranged marriage and her mother turning a blind eye to her struggles, Valeria has one goal: to escape and never be found.
But the bond between mates is impossible to ignore, and when secrets unravel and tensions ignite, Valeria finds herself caught in a dangerous web of jealousy, desire, and betrayal.
Her freedom was all she ever wanted, but will she risk losing her heart to the ones she vowed to leave behind?

Everyone knows the mythology of the gods. What happens if what is known was manipulated by the gods themselves. Our favorite triplets are back. This is their story of how they came to be. Follow along as they grow up and find friends, enemies, and their soul bonds along the way. This is book #2 in the series.
They weren't supposed to exist, yet here they are.
"We have to keep them protected" Zeus roars.
"That doesn't mean we have to keep them locked up." Aphrodite states.
The gods turn as they hear the door opens slamming against the wall. There stand the triples. A look of surprise spreads across everyone's face.
"What the hell did you do to your hair and are those tattoos?" Poseidon asks.
"We dyed it, and yes they are tattoos and we also got a few body piercings" Kylani answers.
"We will not stay hidden away or kept locked up. We have no interest in this life. We are going to walk on the earth with the supernatural and humans. They accept us more than you do." Mykenzie announces.
The girls vanish at that moment. Chris stands there with a look of regret in his eyes. He knew this was coming. They wanted sweet, innocent goddesses like their mother and aunts. What they got was an attitude in a 5'4" package only doubled.
"I told you not to force your ways upon them. They have been independent since birth. You brought this upon yourselves." Hades tells them
The 'Percy Jackson & the Olympians' series by Rick Riordan instantly comes to mind when talking about sibling adventures. Percy and Annabeth might not be blood-related, but their bond feels just as strong, if not stronger, than many actual sibling pairs in literature. The way they navigate Greek mythology, face gods and monsters, and grow together through chaos is both heartwarming and thrilling. Riordan nails the balance between humor and high stakes, making their dynamic unforgettable.
If we're sticking strictly to biological siblings, the 'Kane Chronicles' (also by Riordan) is another gem. Carter and Sadie Kane’s banter and teamwork as they dive into Egyptian mythology is pure gold. Their contrasting personalities—Sadie’s sharp wit and Carter’s steadiness—create a dynamic that feels authentic. Plus, the audiobook versions with dual narrators add so much life to their relationship. It’s rare to find a series where siblings feel this real, with all the squabbles and loyalty intact.
