Pines

Pines by Blake Crouch is pretty similar. FBI agent wakes up in a small town with no idea how / why he got there. Lots of mysteries and very intriguing resolution to the plot. IMO the first book works as a standalone but there are two sequels which aren't very good. It's a case IMO of a book that got way popular beyond an authors expectations so he had to come up with sequels even though the story didn't demand it. First book is really good though with Lost / Silo type of mystery. → The tv show had 2 seasons. The 1st season covered all of the books from beginning to end, so you really could just watch that and be done. The 2nd season continues the story beyond the books but it does have a clear ending.
