The first book to a series of five. I love the Fablehaven series and I have read it over and over again. Its fantasy, about a brother and sister, Seth and Kendra, who visit their Grandparents Sorenson and find out that they actually live on a magical preserve. Then in every book after that they are trying to stop evil people from releasing demons and destroying the world. If you are an adventure book reader, you would also like this series.
