Easily the most engrossing book I've read in a long time. Take science fiction (cloning) and mix it with domestic suspense (murder!) into a very compelling and original plot. Rather than presenting the reader with a babyface and heels, the book has complex characters that lean toward mean because they come from damaging backgrounds. And while I didn't want to root for them, the story drew me in to where I wanted to see everyone have a satisfying end, rather than get what they deserved.

The background of these characters makes the story extremely layered and rich, but a warning. As the author writes in their acknowledgements, The Echo Wife is about abuse, grooming and identity. My abuse was long enough ago, and my psyche is hard to damage these days. The specific situations described are also dissimilar enough from what I faced that I did not have trouble with my own memories while reading. However, there are a lot of people for whom this will be tough reading. Check your headspace before diving in.
