The Mistake - Perfect for fans of T.M. Logan and Liane Moriarty

Bec lives the perfect life: perfect house, perfect husband, perfect children. But something doesn't quite add up, and as he avoids Kate's questions, she begins to wonder if he is too good to be true. Bec thinks Adam is only after her sister's money, and Kate can't see why Bec would throw her life away for Ryan.
