Fablehaven by Brandon Mull

My husband, Blake, and I really like these books. Once again it follows a brother and sister (Kendra and Seth) as they search for artifacts that, if in the wrong hands, will release all the magical creatures that at the moment are left in these magical creature sanctuaries through out the world. One such is called Fablehaven that is taken care of by their grandparents. Through different encounters with magical things, Kendra and Seth have taken on special powers that they slowly realize they have through out the books. I still have not read the last book to see how everything ends, but I am sure it all ends well as most books do. Otherwise, it would not be a terribly good book if it ended horribly. Seth tends to cause a lot of unnecessary trouble for everyone since for some reason he can not listen to others and just stay out of trouble. Instead he insists on trading batteries for gold with the magical creatures and breaking rules that void rules that govern all the magical creatures to keep everyone safe.
