In this book from 2006, Abby Northrup lives in a remodeled monastery and takes in abused women and children. A friend Alicia turns up on her doorstep in the middle of the night with her teenaged daughter. The woman is married to an extremely powerful man. No one expects the FBI to show up a few minutes later. Abby hides them but when the FBI leaves, Alicia is gone.
I have no problem with reading fiction where stories are not very plausible. I'm afraid this one was simply too much. The story became wild and outlandish. Toward the end, I would have to call it preposterous.
