This is a gripping psychological novel. It's a book filled with twists and turns that kept me reading until the very end. Matthias realizes that the girl is not Lena when a women turned up at the hospital. Hannah is the spitting image of Lena. The book is told from 3 different POV's - Lena, Hannah and Matthias. I'm looking forward to reading the next book by Romy Housmann. If you like books like ROOM and GONE GIRL then you will love this book. Highly recommended!
