Anna’s life it turned upside down when a woman shows up as the twin sister she didn’t know that she had. ARC from NetGalley.

This book started off great. However, it started to fall apart a bit when Anna's husband, who was worried about the arrival of an unknown twin sister of Anna's, was skeptical of Amelia (the twin). He is worried for his family's safety, yet leaves for a work trip and tells Anna not to call him! If he was really concerned, he'd stay in touch with his family!
It got better after that, but then when the revealing moment of why Amelia was there happened, the characters just didn't act inline with how they had been acting.
Still, I believe this book will have a large audience, and won't hesitate to recommend it to readers, it just wasn't for me.
