Magpie by Elizabeth Day

I had some downloading issues which may have affected how I felt about this book. 
Marisa and Jake are in love and want to have a baby. They begin fertility treatments and need money so they take in a lodger. Kate, the lodger, then agrees to be their surrogate. She is alway there and once pregnant is even closer to them especially Jake which doesn't sit well with Marisa. Should Marisa worry when it looks like things are going out of control or are over active hormones adding to the situation? The first part of the book is seen through Marisa's eyes with the last half seen through Kate's eyes. There is a twisty end for all you thrill seekers which makes it a great addition to the unreliable twisted thriller category. Fans of B.A. Paris, Lucy Foley, Lisa Jewell will all be happy.  3 1/2 stars
