3.5/5

I'm aware that my rating is probably too high and that even a 3/5 would be generous, but I had too much fun reading this to give it a negative rating even if it's easily the weakest of the series thus far. I know that something a lot of people don't like about this book is Rachel getting amnesia, which I do think is a stupid storyline but I actually quite like the conclusion of it, especially with Cassie's observation of how much getting amnesia scared Rachel because it was a threat that came from within herself, something which is obviously incredibly important to Rachel's character going forward. Tobias does deserve better, though.
