5 stars because it was one of those books I wanted to keep reading even when I knew I should go to bed. The premise: Billionaire Myles Cookson finds out he has Huntingtons disease, it’s going to cut his life short. He decides to find his biological children, fathered via a sperm bank 20+ years ago. However, someone is trying to make those children disappear. Miles and newly discovered daughter Chloe need to find out the truth. Meanwhile there’s a lot of other shady activities going on. Are they connected? It’s been years since I’ve read a Linwood Barclay and now I remember why I always enjoyed his books. I picked it up from the library after someone recommended to me.
