By the time I got to Dreamfever, the fourth book in Karen Moning's Fever series, I was completely and totally addicted. I had finished Faefever in little more than an evening, and started Dreamfever right away. (Again, a significant advantage to ebooks — being able to buy them and start reading them right away.)
This one is longer than others, and a lot happens. I don't want to say too much, for fear of spoiling the first three for people, but to recap, MacKayla Lane has come to Dublin in order to track down her sister's killer. Instead, she discovers a world that she never knew existed, where the Fae live among us and cast their glamour so that we never know it. Mac also discovers that not only is she one of the few who can see them, she is also the only person who can track a magic book that is supposed to be able to save our world from being destroyed by the Fae.
Unfortunately, Dreamfever has possibly the worst cliffhanger ending I've ever experienced, and the fifth book, Shadowfever, isn't due out until January 18, 2011. Believe me, I will be in complete agony until it comes out! I am that excited to find out what happens!
This is a great series for anyone who likes vampire books and dark fantasy. I think they are especially similar to the Sookie Stackhouse (True Blood) books, because the heroines in both are young, blond, pretty, and from the southern United States. Both are also dealing with a completely new world, and supernatural beings they never even knew existed.
Great books — I can't rave about them enough!
