Science fiction and fantasy are officially ruling young-adult books — so it's no surprise that lots of science fiction publishers have been expanding into the YA niche, with often terrific results. The latest addition: Angry Robot Books is launching a YA imprint, Strange Chemistry, headed up by Amanda Rutter. They'll launch next September, with five books by the end of 2012, and one book a month thereafter. Can't wait! [Tor.com]
