There's this book, Fablehaven. It's a series, as well, with over four books 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 composição literária style. The books had a lot of action in it, and a shocking twist at the end of the segundo book was completely unexpected. If you are young like me (I'm 14) or younger, (maybe 15) you should really like Fablehaven. It's nice and thrilling.
