From Publishers Weekly:
Deciding that a standalone adult imprint does not fit with its long-range plans, Disney is selling the majority of Hyperion titles to Hachette Book Group in a deal that is expected to close in mid-July. HBG will acquire more than 1,000 adult backlist titles plus another 25 books that it will release over the next few seasons. Disney will retain the most media-related titles such as its Castle series which ties into the ABC television show of the same name. The book franchises that will remain with Disney will be overseen by Disney Publishing Worldwide. Disney’s children’s imprints, Disney and Disney-Hyperion, are not affected by the sale.
The deal includes the Hyperion name and HBG will continue to publish the Hyperion books under that imprint. Hyperion employees will stay with the company until the deal is completed and will help with transition issues. Some Hyperion employees are expected to join HBG in such areas as editorial and publicity. Other Hyperion employees will be given the opportunity to interview for other positions at Disney.
