Have you ever wished you could know what an author was thinking as they developed their characters, settings or plot twists? Thanks to Lauren and Chelsea, the Leave A Mark auction mavens, now you can! The Leave A Mark auctions are back this fall with more great books “marked up” by your favorite authors and are up for auction to generate new books for kids in need.

Leave a Mark is all about marked up books. That means you aren’t just bidding for a book you could buy in stores or a signed book you could get from a regular signing. These books have notes/behind-the-scenes looks into their story written by the author in the margins or on post-it notes, etc. It’s up to them to decide how they “mark it up.” Even better, 100% of funds from the auctions will benefit First Book, with every $2 donation providing one new book for a child in need.

The first book up for auction is Becoming Chloe by Catherine Ryan Hyde. Bids will be accepted now through Sunday, October 25th at 11:59 P.M. EST.

Be sure to check Leave a Mark blog frequently to see what other great books are being offered in this year’s auction. More details on how the auctions work after the jump.
