The Day he Never Came Home by Andrew Deyoung

Regan Peters knows her husband John wants to give her and their children a good life. The long hours he puts in as a financial advisor prove his dedication, and despite how mysterious he is about his past, that's been enough for her to get through the hard days. Until the FBI shows up at their door looking for John, and Regan learns that her husband has been running a Ponzi scheme, is mixed up with dangerous criminals, and has been living under an assumed identity all these years. Everything she thought she knew about her husband has been a lie.

That includes the outrageous birthday present John gifted her the day before he disappeared—a lake house, bought with cash, and put in her name only. With her life falling apart, Regan must make a split-second decision: does she tell the FBI about the house? Or does she buy some time to forge her own path to saving herself? But one compromise inevitably leads to another, and one dangerous secret builds on the next.

When her lies of omission to the FBI agents begin to raise questions, Regan becomes inextricably embroiled in John's crimes, the true extent of which are just beginning to be revealed. Now that her comfortable life is clearly over, Regan is learning she is capable of far more than she ever imagined. She will do anything to protect herself, her children, and their future. Anything.
