He shouldn’t have imagined her lying naked on his bed. She shouldn’t have imagined his devilishly handsome face between her legs. But it was too late. Kiara began noticing Ethan's washboard abs when he hopped out of the pool, dripping wet after swim practice. Ethan began gazing at Kiara’s golden skin in a bikini as a grown woman instead of the girl next door he grew up with. That kiss should have never happened. It was just one moment in a lifetime of moments, but they both felt its power. They knew the thrumming in their veins and desperation in their bodies might give them all they ever wanted or ruin everything if they followed it. Kiara and Ethan knew they should have never kissed. But it's too late to take that choice back, so they have a new one to make. Fall for each other and risk their friendship or try to forget one little kiss that might change everything. PREVIEW: “If you don’t want to kiss me then... let’s swim.” “Yeah, sure.” “Naked.” “What?” “I always wanted to try skinny dipping. And I really want to get out of these clothes.” “What if someone catches you... me, both?” “We will be in the pool, Ethan. And no one can see us from the living room.” I smirked when I said, “Unless you want to watch me while I swim, you can stay here.” His eyes darkened, and he looked away, probably thinking the same when I noticed red blush creeping up his neck and making his ears and cheeks flush. Cute. “Come on, Ethan. Don’t be a chicken...” “Fine.” His voice was rough when he said, “Remove that sweater first.”

At seventeen, love feels infinite and endings feel impossible. Arielle never planned to fall in love during her final year of high school. Noah never planned to let his guard down. But when quiet glances turn into late conversations and unspoken feelings surface, they find themselves caught in a connection neither of them is ready to name or walk away from. Set against the fragile edge of senior year, Promises We Made at Seventeen is a slow-burn, dual-POV romance about first love, fear, and the weight of choices made too young to fully understand, yet too deep to ignore. As expectations, rumors, and the future press in, Arielle and Noah must decide whether honesty is worth the risk and whether promises made before adulthood can survive what comes after. Tender, dramatic, and emotionally raw, this story explores what it means to love someone while still learning who you are, and how some promises no matter how small can change the course of a lifetime.

In the chaos and quiet of her 30s, a woman reflects on the loves that shaped her, the heartbreaks that undid her, and the tender spaces in between. Through fleeting romances, almost-loves, and the weight of expectations—family’s, society’s, and her own—she navigates a world where connection is currency, vulnerability is rebellion, and self-discovery never comes easy. Told with wit, warmth, and raw honesty, this novel is a journey through modern love: messy, magical, and sometimes maddening. It's about the people who entered her life, the ones who left, and the version of herself she’s still becoming.

Amara Bennett has a rule: Never let anyone close enough to break your heart twice. After a humiliating breakup that turned her into the laughingstock of her school, she’s done with romance, done with hope, and definitely done with boys who make promises they can’t keep. Then Julian Reyes transfers into her class. Charming without trying. Annoyingly kind. The type of boy who remembers little things—like how she hates strawberries on cake and how she always pretends she’s okay when she isn’t. At first, Amara can’t stand him. Mostly because Julian somehow sees through every wall she built around herself. But when a misunderstanding makes the entire school believe they’re dating, Julian offers her a deal: fake a relationship until the rumors die down. Simple. Except nothing about Julian feels fake. Not the way he waits outside her classroom just to walk her home. Not the way his hand finds hers during crowded hallways. And definitely not the way he looks at her like she’s the best thing he’s ever found. For the first time in a long time, Amara begins to believe love might not be something meant to hurt her. But just when she finally lets herself fall, she discovers the truth Julian has been hiding since the day they met—a truth that could destroy everything between them. Because Julian didn’t transfer to her school by coincidence. He came for her.
