I received an advance review copy for free, and I am leaving this review voluntarily. Elsa is a teacher and a mother who has always been convinced her son was switched at birth. When she meets a student that looks like he could be her biological son she gets serious about getting to the bottom of it. The chaos and secrets in this book were heart wrenching and this plot was packed with all different emotions I felt as I read. What could happen to the son she thought was hers and has loved for all these years? This book grapple with impossible feelings and really had me pulled in and invested. The plot was genius to begin with but the way the characters were developed and interacted was beautifully done. This is a book to treasure forever.
