This wonderful book is the best book I've ever read (Actually, I read it in Hebrew, where it's called לב של דיו (Lev shel dyo; translation: Heart of Ink)). Originally written in German, the book was translated into many languages, including English, Hebrew and more.

The book tells the story of a girl named Meggie who suddenly finds her life changed by a mysterious stranger (later known as Dustfinger) standing outside at night. Meggie meets a horrendous villain - Kapricorn, one of the main characters in the story. Meggie finds out that she has a wonderful but dangerous power which she had inherited from her father, Mortimer; she finally understands why he had never read to her out loud. 

This book made me think for at least a day, and even after reading the next book, I think Inkheart is the best in the series. I especially like the part where Meggie reads out loud, and also the beginning.
