It’s no Midnight Sun “ Stephenie Meyer’s Twilight Saga story written from Edward’s perspective, which was leaked in 2008 “ but Meyer’s publisher, Little, Brown for Young Readers, announced today that a new novella is coming on June 5. The Short Second Life of Bree Tanner tells the story of a vampire in the newborn army (the term refers to her newfound vampirism “ the book isn’t actually about baby bloodsuckers). The eponymous character was introduced in Eclipse, the third book in the Twilight Saga.

The initial print run for the 192-page book will be 1.5 million copies, and $1 from all U.S. book sales will go to the Red Cross to help relief efforts in Haiti and Chile. As a thank you to intensely devoted Twihards, the book will also be available for free online from June 7 to July 5.

The manuscript has been kept tightly under wraps so far, although Meyer gave copies to the director and a few cast members of the film adaptation of Eclipse, so all the parties involved would end up having a really strong foundation for their characters before the cameras started rolling, Meyer said on her website. After reading it, though, they literally had to burn their copies to keep the story from leaking. Bree Tanner was originally intended to be included in the upcoming The Twilight Saga: The Official Guide as a short story, but it expanded until it would no longer fit in the guide. Meyer said this about the new book:

I began this story a long time ago ” before Twilight was even released. Back then I was just editing Eclipse, and in the thick of my vampire world. I was thinking a lot about the newborns, imagining their side of the story, and one thing led to another. I started writing from Bree’s perspective about those final days, and what it was like to be a newborn.
