All Aces by Ellie Marney

Nineteen-year-old contortionist Ren Putri is committed to circus, study and self-discipline – in that order. But after being rescued from a carnival fire by cardsharp Zep Deal, she’s overwhelmed by some highly disorderly thoughts. Zep has a history of trouble, and now he’s been suspected of sabotaging the circus that’s become his whole life. Ren is already coping with family, and keeping secrets of her own – but she can’t resist a mystery. Will Ren’s penchant for solving puzzles bring the case against Zep to rights, or will digging further into the bad blood between rival carnivals only put them both in danger?
