Hi! I love Fablehaven. I tell the stories to my little brother and he loves them, too. I've read all the books & I'm waiting for book 4 to come out.

For PowerGirl:
Fablehaven is about these two kids Seth and Kendra who find out about a secret magical creature preserve called Fablehaven and an evil society called The Society Of The Evening Star. In book one they have to stop a witch, in book two they have to stop an evil frog demon and the Evening Star, and in book three they have to find out the mystery of a darkness plague that is turning magical creatures into creatures of darkness.
