Sonic Underground Siblings Novels & Stories

My father scoured the underground markets and bought my sister and me a pair of twin wolf-blood slaves. Catherine snatched the tall, powerfully built brother first—his alpha scent already awakening despite the silver shackles. That left me with the scrawny, silver-poisoned "cripple" whose wolf seemed permanently dormant. I pitied the poor bastard. His wolf was so suppressed I could barely catch his scent, so I kept him close, hoping my presence might help him heal. His legs were useless, twisted from what looked like forced silver injections. I dragged him to every back-alley healer and rogue pack doctor I could find, desperate to purge the poison from his system. I figured some brutal werewolf hunter had shattered both him and his wolf. Until my dad's rival pack snatched us both during the blood moon. He exploded from his wheelchair in a surge of raw alpha power, his true scent hitting me like a freight train. Golden eyes blazing, when my father's enemy aimed a silver gun at my sister, he grabbed me and shielded her from six bullets. "I'm sorry, Catherine can't die. I'll make it up to you in the next life." That's when it hit me—he wasn't crippled, wasn't even an omega. The silver poisoning? That was all just for me. I blinked... and woke up on slave-picking day. This time, I set him free.

Three years ago, my fated mate, Rex Hemmond, had personally signed the auction contract, resulting in me getting delivered onto the auction stage in the black market. That night, I was injected with aphrodisiacs, leading to me revealing my most debauched side in front of everyone. That was how I became the most hated harlot in the Moonshade pack. My sister, Daisy Russell, could be seen nestling into Rex's arms. She was smiling as she watched me fall into the abyss. During the years of my exile, I spent countless nights beneath bridges. Most of the time, I was chased around by others who wanted to beat me up. Eventually, I started earning money by slaving away in underground cage fights as a fighter so that I could buy back the estate that my dad had left me with. Three years later, Rex tracks me down with bloodshot eyes. "Come back with me and apologize to Daisy." I respond by punching him in the face. "That'll be 100 dollars per punch. If you're still unsatisfied, you can keep punching me." When Rex takes Daisy's hand at the estate's gateway and claims that it will be hers from now on, I finally fire a text message to an unknown number. "I need you." The moment that wolf steps into the Moonshade pack, Rex questions me with red-rimmed eyes, "Since when did you get together with him?" I just smile in return. "He was the one who saved me on the night you signed the auction contract."

I was born with a one-track mind—I take everything seriously and do exactly as I'm told. When my adoptive father cursed a rival company, calling them bloodsucking vampires, I immediately went out, bought ten pounds of garlic and a crucifix, and stormed into their CEO's office to perform an exorcism. When my adoptive mother said she was willing to sell a kidney for the sake of the company, I contacted an underground black-market clinic on the spot and asked when they could schedule her surgery. Over time, no one dared joke casually around me anymore. Everyone in the family chose their words with extreme care, terrified I might take them at face value. That is, until the day of the family reunion banquet—when the fake heiress, who refused to leave no matter what, showed up as well. She hooked her arm through my brother's and flashed me a provocative smile. "Arista, Benji dotes on me the most," she said sweetly. "He said if anyone dares to make me unhappy, he'll chop them into pieces and dump them in the river to feed the fish." The banquet hall erupted in laughter. I was the only one whose face went deathly pale. The next second, I kicked my brother, Benji Collins, straight onto the dining table. I grabbed the silver steak knife and pressed it against his throat. "Everyone, stay calm," I announced loudly. "I've already called the police! For publicly advocating premeditated murder, desecration of a corpse, and antisocial personality tendencies… The minimum sentence is the death penalty!"

Just as the Silverwolf Pack was about to fall into ruin, Blaise Larkin approached me and asked me to be his mate. I'd had a crush on Blaise for as long as I could remember. Now that my wildest dreams were about to come true, I was happy to form a mate bond with him. As I was the sole daughter of the Eastern Pack's Alpha, I was able to provide him with a mountain of resources by becoming Blaise's mate. One month after our bonding ceremony, I was expecting a pup. I was ecstatic, but before I could share the news with Blaise, I overheard something soul-shattering. "I wonder who fathered the pup of our pregnant Luna." "She probably got involved with some filthy Rogue. There's no way Alpha Blaise will let her give birth to that mutt, right?" If it weren't for those werewolves, I wouldn't know that Blaise was pretending we never mated. When I demanded answers in a deranged manner, he threw me into the underground prison and forced me to atone for the death of his first love. "If you didn't insist on becoming my mate, Susie wouldn't have left the pack—she also wouldn't have gotten slaughtered by Rogues!" Eight months later, I lost my pup in the cell I was imprisoned in and died, soaking in my own blood. When I opened my eyes once again, I found myself back on the day Blaise asked me to be his mate.
