I read the first book in this trilogy, Shiver, in the summer of 2014. That book was given to me by a friend, along with a ton of others, but it caught my eye from the day I received it. It's sort of the book that got me back into reading after a 6-ish month slump. I enjoyed it, finished it in a couple of days, and I'm not sure why I didn't pick up the other books sooner.
This book was good enough to keep me up until nearly midnight on the night that I started it. It's well paced, the action isn't cluttered but there's also never a dull moment. It's a good continuation of the original story, though I almost wish that it didn't end in such a cliffhanger, because it will probably be a little while before I get my hands on the next book. At the same time, though, I really enjoyed the ending. It gives something to look forward to upon starting the next book.
Due to so many negative reviews of these books, I guess you can say it's become my guilty pleasure series.
