Fablehaven book 1, by Brandon Mull

Fablehaven, book 1 by Brandon Mull begins the exciting careers of Kendra and Seth Sorenson when they first go to Fablehaven, a magical preserve that their dad's parents are caretakers of.

The two, mostly because of Seth being an idiot, get into all sorts of trouble and danger, and find themselves in a situation where they need to rescue others. When the rescue operation goes awry and Kendra is the only one who can do anything to save the others, will she just give up? Or will she find a way to save everyone? This is a great middle grade book, but anyone who enjoys magical adventures would like it.
