The Kind Worth Saving is a follow-up to the 2015 novel The Kind Worth Killing. You don't strictly have to read the first one to enjoy this one, but I highly recommend you do as it will help you to better understand the main characters and their backstory. I am a huge fan of Peter Swanson and the first book was what started it all for me so I was eager to read this one and I'm happy to say it didn't disappoint. Swanson's writing is superb and hands down he is one of the best crime thriller authors out there. His characters are so detailed, realistic and likeable. I'd give this more than 5 stars if it was possible. Highly recommend.
