First of all, you need a couple of days free to start this series because once you start, you'll get 'fever' and can't put the series down until you finish. I must say it, the first book initially started off a little slow for me but once it picked up, IT PICKED UP. The characters & the story was so captivating. I felt an obsession of needing to know how it ended at the same time, not wanting the series to end at all. It's such a great read, and Shadowfever didn't disappoint at all.
