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