Book & Bone (Oneironaut #1)

Oryn Academy has tasked its brightest students with finding the cure for Sleepbane—a thousand-year-old sleeping plague that has eradicated millions. When two of those students, Minkka Greyfell and Faxon Fletcher, realize something is amiss, they rebel against the establishment, splintering off to search for the cure on their own. Their journey takes them into a world of peril where life-and-death decisions can mean saving their homeland … or plunging it deeper into darkness.
