When Raquel wakes up one day in college, things feel a bit weird - and get weirder when birds fall from the air, the sky turns a funny colour and it begins raining giant rocks that promptly kill Raquel. When she wakes up, it's two years in the past and she's 16 again. She soon discovers that there are others who experienced the end of the world and sent back in time, and they have to work out what happened and how to save the world.

This was....okay? I thought the time travel the teens discovered they could do and how they looked back at other civilisation ending catastrophes to figure what happened to them was quite interesting, and not something I've read about before. But overall, everything seemed a bit too easy for them and how they figured everything out (the end was a bit anti-climatic too). There wasn't really an explanation as to how they ended up time travelling, and how their powers worked other than 'Memory' as well as why Chris and Raquel were the only ones together and who knew each other from before. I did keep laughing as well in how Raquel kept stressing how much mature and adult she was from her 16 year old friends because she was mentally 18 and had experienced one whole semester in college, and while yes I see her point, there isn't actually that much difference from 16 and 18. It would have made a bit more sense if she was mentally 21 and had to time travel back to her 16 year old self.
