There's this book, Fablehaven. It's a series, as well, with over four boeken in it. It revolves around Kendra and Seth Sorenson as they go to their grandfather's Estate. They discover a secret magical preserve, which they quickly learn is in danger from the Society of the Evening star, an evil secret society. Brandon Mull is the author, and he uses a very good writing style. The boeken had a lot of action in it, and a shocking twist at the end of the seconde book was completely unexpected. If u are young like me (I'm 14) of younger, (maybe 15) u should really like Fablehaven. It's nice and thrilling.
