I love books about sisters, probably because I don't have one of my own. I wonder if I would believe someone if they claimed to be my half sister! I have a copy of The Other Woman by Sandie Jones but I haven't read it yet. I do know she is a great thriller writer! This book starts with a scene in a clinic for fertility treatments, which is a topic I enjoy reading about. I look forward to finding out about the half sister who interrupts a family get together.
