So where does Sarah Palmer come from? Find out reading Initation

Wired explains about a new Halo novelization of Sarah Palmer's back story called Initiation:

Brian Reed, the comic writer who adapted the Halo: Fall of Reach novel into comic form in 2010 before joining 343 Industries to write the Halo 4 game, will write the books, with Marco Castiello (Star Wars: Purge) on art. Initiation is the origin story of Sarah Palmer, a character introduced in Halo 4.

Although she appeared in the game as a commander of the Spartan forces, she was originally an Orbital Drop Shock Trooper; this series follows her career path.

“After Halo 4 and Spartan Ops, fans wanted to know more about the origins of the Spartan-IV program and Sarah Palmer in particular. So it’s great fun to be able to grant those wishes with a partner like Dark Horse,”
