For me, this book was quite good. I neither love it nor hate it. It's fast-paced, thrilling and full of exciting twists. You're probably wondering why I don't LOVE it? Meh, I like action books, but romance and paranormal mysteries remain my favourites, which is why this book isn't up there.
One character did irritate me throughout this book-Ketty. She seems quite childish and weak in comparison to some of the others, and is oblivious to the fact that Ed is better than Nico. But, on the other hand, I did like the other characters.
Dylan was quite interesting. Her medusa power isn't as mentioned as the others' but it's still pretty cool. She does use the word 'freaking; a lot, and I did want a bit of a change sometimes, but that's just a silly, small point.
Either way, if you want a short, exciting read then this is ideal. The characters don't stick with you, but the story keeps you hooked.
