What a thrilling ride. This is my first book by Barclay but it won't be my last. I read 300 pages in one afternoon!

Miles is a tech genius/millionaire who finds out he has Huntington's disease. So many years ago, he donated at a sperm bank and finds he has at least 9 biological children out there that have a 50% chance of inheriting the same disease.

But soon, he finds they are being hunted and killed off one by one. Who is taking away their chance to inherit?

Wow, this was just so twisty and even though I guessed a lot of what's revealed at the end, I was so enthralled by the story. I liked Chloe, his first found child and how she doesn't care about any money she might get. I like the two of them trying to save the others together.
