Bookword Game: New Word and Suggestions Needed

The winner of our latest bookword (with 86% of the vote) is:

Title Block: what we call a book where you can remember its plot, but not the title, suggested by Melissa from One Librarian's Book Reviews. Congratulations!


On to the next word! What should we call a book that seems to take on a personality of its own and call out to you to "please read me NOW" and is very persistent about it and won't leave you alone until you've read it. Or, in shorter words, what should we call a book that begs to be read immediately?

Suggestions in comments! Poll next week at An Adventure in Reading! And come on guys, we can do better than just TWO suggestions this week, right? Of course right! :)
