Exhausted by her two small children, Emma isn't sure what put-together Nina sees in her. Unknown to her, Nina remembers her from the past, and is now playing a dangerous game of cat and mouse with her life. The description was intriguing, but the details and the execution were lacking.
For the first third of the book, although we learn that Nina remembers Emma from somewhere and that she orchestrated their new "meeting," Nina and Emma barely interact. Once they finally become a regular part of each other's lives, the tension does increase somewhat. But when the reader finally learns what it was that Emma did years before that makes Nina want revenge even though Emma doesn't even remember her, it's anticlimactic. It turns out that the thing Emma did wasn't deliberately cruel. She probably didn't intend to do it and it's entirely possible that she was never even aware it happened. Most of the book's chapters from Nina's perspective build suspense over how she knew Emma and why she wants revenge, and when it's finally revealed.... nothing. Then it ends abruptly without Emma apparently ever having found out what Nina was doing to her or why. This book is in need of a catharsis it's lacking.
Her will be available in the U.S. in January 2015.
