The cover of The Echo Wife by Sarah Gailey is very interesting, it drew my attention right away and gives a hint about what the book is about. I was immediately intrigued by the initial summary and couldn't wait to read more. It sounds like a great medical thriller as well as a story about how relationships can go wrong. Evelyn seems like a work obsessed scientist but it is clear that underneath that obsession is a real woman mourning the loss of her marriage. And of course I can't wait to find out more about Martine because there is definitely more to that story!
