Actor-writer Jason Segel has scored a deal to write another scary series of young adult books. The "Forgetting Sarah Marshall" star previously teamed up with author Kirsten Miller to co-write Nightmares!, which became a staple on The New York Times bestseller list, and now he's joining forces with Miller, as well as publishers at Delacorte Press, for a trilogy titled Otherworld, which centres around a teen gamer who disappears into virtual reality "Connecting with the readers of the Nightmares! series at events has been a truly special experience for me, and I am incredibly excited to have the opportunity to keep writing stories for these readers, and to grow with them into young adults with Otherworld," said Segel.
