Bukkit

Thank you very much for your plugin! I really love it. I have a single problem, I can't give pre writen books. I made a book.txt file in the plugin folder, I restart and appears

"This is the book file."

Then I write a "book" example:

This is the book file.

#My_book
This is a example book. Book End.

Later I restart again and  copy-paste  my essentials command
/give "an_user" 387 1 title:Example_book author:SomeGuy book:My_book.

But te result is a book tellingme something about bad tags, I try it the same in my 1.7.x server with essentials and works :S ¿Can you help me? Thanks for reading me!
