Well, that was a journey and a half. Did I actually dislike this as much as some of the course books of the same rating…probably not. However, I really really didn’t like this and for several reasons.  
1. I wanted to like it so much. Miss Butt I would trust you with my life but evidently not with book taste. My high expectations definitely resulted in this falling so short
2. This book refuses to accept the creepy and paedophilic nature of its own existence. It is so uncomfortable at so many points and yet it’s weirdness is apparently ignored in favour of the plot. 
3. It’s approach to many of the themes it touches on is so insulting. From its use of derogatory language towards disabled people and the queer community to its non chalante approach to the concept of rape (a word used as a synonym for eagerness in many cases and then not addressed in cases where consent is actually not confirmed). This adds to the uncomfy nature of the book and honestly made me want to DNF it throughout 
4. The concept is so good, the execution is awful- I wanted so badly to love this idea of spontaneous time travel but the way it is used, and the sexual focus of the story just made it fall short
5. There is no character development. Literally how? you are focusing on the same group of people across all of there lives- why are they so boring?
