Also published as Guys Read: Other Worlds, this is the fourth volume in the Guys Read anthology series created and edited by children's author Jon Scieszka, with illustrations by Greg Ruth. Built around Scieszka's literacy mission to win over boys and so-called reluctant readers, each Guys Read volume gathers short, high-interest stories in a single genre; this installment takes on science fiction and fantasy, collecting roughly ten tales of robots, ghosts, stranded colonists, mythic quests, and stranger things still. The lineup brings together prominent authors of children's and young-adult fiction, including Tom Angleberger, Shannon Hale, Kenneth Oppel, Rebecca Stead, Eric S. Nylund, D.J. MacHale, Neal Shusterman, Shaun Tan, and a reprinted classic from Ray Bradbury. Rick Riordan appears here as a contributor, not the author or editor: his story, Percy Jackson and the Singer of Apollo, is a Percy Jackson tale in which Apollo asks Percy for a small favor that turns into a big problem when a runaway singing automaton, a celedon, must be tracked down. The volume's variety of voices and genres is the point, offering reluctant readers several short, punchy entry points rather than one long narrative. For fans coming specifically for Riordan, his story is a single, self-contained piece within a much larger multi-author collection.
