Some hearts are harder to control than the fastest cars. Isabelle Carter has always had a weakness for speed. The roar of engines, the thrill of competition and the freedom of the open road make her feel more alive than anything else. At eighteen, she's a high school girl with a sharp tongue, a stubborn streak and a smile that can make her look innocent right before she gets herself into trouble. Her expressive eyes give away more than she'd ever admit, while her effortless charm and confident attitude make her difficult to ignore. Isabelle isn't the kind of girl who backs down easily and she certainly doesn't like being told what to do. Her best friend, Mia Johnson, is never far behind. Mia is the lively, quick-witted girl who can turn an ordinary school day into an unforgettable adventure. With her bright, expressive eyes, radiant smile and naturally charming presence, she has a way of drawing people in without even trying. She's playful, dramatic, fiercely loyal and always ready with a sarcastic remark. But beneath all that humour is a girl with a tender heart who feels more deeply than she lets people see. Together, the two high school best friends have mastered the art of getting into trouble and finding a reason to laugh about it afterward. Unfortunately, Isabelle's parents have other plans for her. Racing is forbidden, trouble is unacceptable, and boys with dangerous reputations are strictly off-limits. Then she meets Axel Moretti. Tall, broad-shouldered and effortlessly intimidating, Axel has the kind of presence that turns heads without him even trying. His dark, captivating eyes seem to hold a thousand secrets, while his sharply defined features and crooked smile make it difficult to look away. At twenty-three, he's already made a name for himself in the underground racing world, where loyalty is fragile, rivalries run deep and mistakes can cost more than money. He's arrogant, unpredictable and far too charming for his own good. Isabelle is stubborn, outspoken and completely unimpressed by his attempts to get under her skin. Their first encounters are anything but peaceful. Their arguments are relentless, their chemistry undeniable, and the attraction between them becomes harder to ignore with every passing moment. Meanwhile, Mia discovers that falling for someone might be just as terrifying as she always joked it was. But Axel's world is built on secrets, and Isabelle's family may be connected to a past neither of them understands. Between midnight races, jealous rivals, unexpected friendships and feelings neither girl planned for, Isabelle and Mia are about to discover that growing up can be just as unpredictable as life on the racing track. Because sometimes, the most dangerous thing isn't getting behind the wheel. It's falling in love.
