I bought this book after reading The Sinner by the same author, which i'd give a 5* rating. I was dissapointed to find that of all her books, only these 2 so far as translated into english. I had very very high hopes for this book. The basic concept which the reader must accept at the start is that 2 women, completely unrelated look so uncannily alike, that one woman can step into the others 'shoes' and take over her life for brief periods. The imposter is coached by the woman whose life she takes over, its a willing transaction with benefits for each woman. The imposter is expected to fool the husband and friends of this lady. But I struggled through the entire book with this concept and thus the book was ruined for me. The book is very well written, i enjoyed the twists and turns of the plot. I warmed to the main characters. But throughout the book when the imposter is living the life of the 'other' character, i just felt that the author was expecting me to suspend a bit too much belief. For other readers this might not be an issue, but for me, it bugged me too much.
