First off, when a book is written by Colleen Hoover and Tarryn Fisher you know it is going to be good. Little did I know just how good it was going to be!! I finished reading it with a WTH just happened and kept hitting my iPad hoping the page would turn!! What would it be like to all of a sudden not know who you are or anything about you. Charlie and Silas are living it and trying to find out how. Their lives up until this clearly had some questionable actions but is this a way to redo those mistakes? Make up for being mean people? Righting their wrongs? Who the hell knows!! This book leaves know clues has to how or why this is happening to them. If it does, I need to read again and find it because I thought for sure I could figure it out. I could not put it down which also means I have awhile to wait for the next one. This is one of those books that will keep you thinking after you are done with it. A storyline I have not seen.
