Book excerpt: This is the 1st episode in the third season of Bookburners, a 13-episode serial from Serial Box Publishing. This episode written by Max Gladstone. Magic is real . . . and hungry. Sal and Liam run into trouble at the Lascaux caves . . . and find themselves sucked in to the art a bit too literally for their taste. Unexpected help comes when Sal's brother-now half angel, half human-shows up after a year's absence, but can they trust him? And does it really matter what he's done in the past if he can help them get out of the caves now? Things have changed for the Vatican's magic-fighting Team Three: their forces are depleted, and internal rifts are coming close to tearing this close-knit group apart. But some things never change. Magic still threatens to overwhelm our world, and when a startling appearance from Menchú's past reveals new dimensions to this danger, the team will have to reassess their loyalties-to their jobs, their beliefs, and even to each other.
