For starters go into this book blind! Try not to read to far into it and definitely don’t read a bunch of reviews because the fun of a thriller is getting that solid thrill all on your own. And boyyyyy do you get it with this one! Just whenever you think you have something pinned down or figured out it slips through your fingers and is gone before you know it. Assume nothing and just enjoy the unknown for once. The characters though somewhat confusing made so much sense once you finally make it a good way through the book and although slow at some points it picks back up in all the right places and left me with a feeling of satisfaction. I never once correctly guessed the ending or what exactly was going on so it definitely lived up to the category of a thriller!
