Sophie's life comes apart one week before her wedding. Instead of revenge, she chooses survival: cancel the plans, move into a smaller apartment, and figure out who she is without the future she thought was guaranteed. Then Callum—her ex-fiancé's younger brother—keeps showing up with the kind of quiet care that never asks for more than she can freely give. He doesn't try to save her, and she doesn't want saving. What grows between them is slower than desire and steadier than rebound: trust, honesty, and the chance to be chosen without losing herself first. After the Cheating is a warm, emotionally grounded contemporary romance about betrayal, consent, recovery, and building a new life on purpose.
