The It's One of Us

If you're a fan of plot twists, surprises, and thought-provoking stories, you won't be able to put down this excellent psychological thriller. But it's not just a page-turner - the author also tackles challenging moral issues, such as marital secrets, infertility, mental illness, and the controversial world of unregulated sperm donation.

As you continue reading, you find out that there were murders that took place - including one that happened twenty years ago, which may have been solved wrong. On top of that, the killer's dad has a lot of kids (who don't even know each other!) connected through the internet. This book keeps you guessing for sure.
