The writing style captivated me that I didn't realise I had been reading for 2 hours before taking a break. This very rarely happens.
Although I felt like I had read something similar to this before I still really enjoyed this. Certain things I saw coming, however I don't think they were plot twists so it didn't bother me too much.
I wish the run up to the ending started a little earlier. I felt like it was a little rushed the last 15%
