Houston, we have a cool book promotion. Beth Revis’ Across the Universe series comes to a close Jan. 15 with Shades of Earth. To celebrate the third and final book in the series, Revis has partnered with Penguin for a literal book launch. If fans pre-order more copies of Shades of Earth than they did for books one and two combined, they will launch a copy of Across the Universe into space. (Picture something similar to this.) Watch Revis explain the promotional campaign after the jump.
