The start of a new series by Martha Wells, creator of the phenomenal Killerbot Diaries! Loon has spent his entire life hiding who he is: a werewolf with the ability to transform into a winged flying creature. An orphan with only vague memories of his past, he tries to live in the River Valley Tribe, but still feels isolated and alienated. Just as he is once again cast out by his adopted tribe, Lung discovers a werewolf just like himself. The creature seems to know exactly who he is, and promises to help Luna be accepted into the werewolf community - the Raksura. Only this stranger does not say that Luhn's presence will upset the balance of power and that his distinguished lineage is crucial to the survival of the colony and his people facing extinction at the hands of a terrifying evil. Now Lung must overcome internal barriers to save himself... and his newfound brothers and sisters.
