Ugh.. this was not for me. The writing style was tedious and overly descriptive. The characters were flat and unrealistic - I'm sorry but 18 year olds don't call each other child or talk like that in any way. I hated the friendship - they were all toxic and genuinely awful. And the amount of repetition... I started to just skip entire pages because I was sick of it.
I did like the time travel-y portion. It was crazy unique and interesting. And the mystery story line is what made me finish the book (although the conclusion was SO disappointing)
