Shade, the runt of his bat colony, gets lost during a storm while migrating. He and another bat undertake a journey and quest and are threatened by an endless series of adversaries: the city pigeons, a kingdom of rats, the onslaught of winter, and two vampire bats. Oppel has combined factual elements of bat behavior with elements of traditional animal fantasy to create a fully imagined nighttime world.

A small bat's curiosity touches off a war of extermination against all his kind in this action-packed odyssey from the author of Dead Water Zone (1993). In satisfying his desire to catch just a glimpse of the sun, young Shade defies a punishment imposed millions of years before when bats refused to fight in the Great War Between the Birds and the Beasts. In swift retribution, owls burn the ancient nursery of the silverwing bats, forcing them to depart early for Hibernaculum, their winter roost. A sudden storm blows Shade away from the flock; in the chase to catch up, he meets Marina, a faithful companion of another bat species; acquires a nemesis in Goth, a huge, seemingly indestructible tropical bat with cannibalistic tendencies; escapes capture above ground and below; encounters a host of allies and enemies; and finds several mysteries to pursue—why other animals are so ready to wipe the bats out, what the silver bands humans give some bats portend, and especially what became of his banded father. Replete with appealing characters, scary adversaries, bat lore, natural history, unanswered questions, and conflicting theologies, the story takes on a promising epic sweep; readers will look forward to the sequels that Oppel's ending guarantees. (Fiction. 11-13)"

Gr 4-6--The plot of this book sounds like the perfect adventure for a noble hero: a dangerous journey with a cryptic map and a trusty companion. But here's the catch: the hero is an undersized bat. Shade, a newborn Silverwing, is separated from his colony during their winter migrations. With the help of an exiled Brightwing, he must find his colony and save them from marauding cannibal bats imported from the tropics. In an author's note, Oppel writes that he "liked the challenge of taking animals that many might consider ugly' orscary' and fashioning them into interesting, appealing characters"; he has done just that with Shade and his comrades. While these characters are not particularly well rounded, readers will sympathize with the young bat's sometimes foolhardy efforts to prove that he's more than the colony runt, and the villains--fire-carrying owls and six-foot, flesh-eating bats--will keep even reluctant readers engaged. However, the greatest strengths of this story lie in its fast-paced, cliff-hanging action and its setting within the hollow trees and bell towers of the bats' monochromatic nighttime world. Recommend this one to fans of Avi's Poppy (Orchard, 1995); they won't be disappointed.--Beth Wright, Edythe Dyer Community Library, Hampden, ME
