Book Four until further notice is my favorite book of this series.

Bill is off doing research for his database of vampires and isn't featured much in this one.  Yay!

Sookie is feeling pretty shell shocked and sick of her current life.  She tries to lay low but one night low and behold Eric shows up half naked and without a memory.  Some bad witches are in town and put a spell on Eric for refusing to play nice.  Sookie takes care of him while the other vamps try to figure out a way to get the spell removed.  The memory-less Eric is sweet, a little timid, and more affectionate than normal Eric.  It takes a few chapters before Sookie joins Team Eric.  And really, who wouldn't want to join Team Eric.

This plus a big battle at the end between the Vamps, Weres, the local Witches and Wiccans, and Fairies versus the bad Witches won me over.  

Oh, there's a Plot A.  Jason disappears which really isn't such a big deal but Sookie suspects the bad witches have played a part.  He eventually shows back up at the end...a little worse for the Were.  Ha.
