Very very disappointing. Combination of a boring storyline, poor writing style, and really anti-climatic suspense.
It was so bad that I really struggled to finish it.
SPOILER ALERT:
the whole story centres around these silly little russian dolls which makes Finn anxious. over and over again: russian doll, russian doll, russian doll. Followed by...was it Harry? was it Ruby? was it the neighbor?
....
I'm sorry, but genuinely feels like i've wasted my money on this. appalling considering the number of great (and im sure, FAKE) reviews online.
