First of all, Ruth Ware and Lisa Jewell are two of my all time favorite authors!! So when I read that tag line I said, I need this book in my life right now! Then i read on. The premise sounds so good. Loving the suspense against the tropical background. I can see this being a real page Turner! I want to know all about this family that Emily has stumbled upon. What makes them so interesting? Will emily figure it out in time? And the cover is beautiful! Really eye catching!
