Grip of the Shadow Plague, Fablehaven 3
In the third book of Fablehaven Kendra and Seth go through even more action and adventure than the first two. Kendra, who has been invited to become a knight, is lead in a different direction and taken to a reserve in New Mexico for a trip full of action and interesting new characters. Seth - staying back at Fablehaven finds himself in an adventure of his own when a dark plaque starts covering the whole reserve.
I have to insert some thoughts on series. Series books are some of my favorite reads. Sometimes I have a hard time picking a favorite out of the entire series (The Pemberly Chronicles, The Work and the Glory, Goose Girl), sometimes I have obvious favorites(Harry Potter, Twilight) and sometimes I feel the series gets better (Harry Potter, Fablehaven,) - or worse (Uglies) as the series continues.
I think this series is getting better. I didn't love one and two as much as three. I've heard four is even better. I'm glad this series isn't fitting into the getting worse category I do think that kids would love them!
