Dracula

The book I am currently reading for English class is "Dracula" by Bram Stoker. This book is written in diary format. In the begining it's Jonathan Harker's diary. he is a soliciator who is sent to Castle Dracula. At the castle he meets Count Dracula and as time passe he realizes that he is a vampire. At first this book was really amazing but then it completely stops with Jonathan's diary and we switch to his fiances Mina's diary. Then it goes on to her best friend Lucy's diary. I haven't finished the book yet but its been over 150 pages with no mention of what happened at Castle Dracula after Jonathan discovered his was alone with a vampire and tried to escape. overall it is a pretty good book so far.
