In the video embedded above, YA writer John Green revealed the title for his new book (The Fault in Our Stars) and promised to sign every single one of the 150,000 books in the first print run.

Even though the manuscript is currently unfinished and the cover has yet to be finalized, the title hit #1 on the Amazon and BarnesandNoble.com bestseller list recently. Green said the publication date has been moved up from May 2012 to January 2012. The author will be video-recording himself throughout the entire signing process; the video will be available on the Vlogbrothers YouTube channel he shares with his brother, Hank Green.

Here’s more from Green’s announcement: “I am doing this because 1. I like my readers, and 2. I want to find a way to thank them for choosing to read my books in this media-saturated world, and 3. I can’t tour everywhere, and it seems weird to preference readers who live near big metropolitan areas of the US over other readers, plus 4. I think it will be kind of fun unless my hand falls off.”

The new book’s title was inspired by a line from Cassius in William Shakespeare‘s Julius Caesar.  Green is currently polling his fans to decide what color sharpie to use for the signing. One enthusiastic fan actually sent Green a box of 140 green sharpies. What color do you prefer?
