Former New Line execs Michael Lynne and Bob Shaye have signed on Nick Pustay (Ramona and Beezus) to adapt supernatural romancer Shiver, for their Unique Features shingle.

According to Variety, Shiver was penned by Maggie Stiefvater, and centers on a bittersweet romance between a teen girl and a boy who becomes a wolf each winter. As the temperature drops, the race to keep him human begins. First installment was published by Scholastic Press in August and has been on the bestseller lists for 31 weeks.

"At the core is this heartbreaking love story, between two people who know that their time together is slipping away," Pustay said.

No production date was announced.
