Frostbite is a werewolf novel by David Wellington, serialized online in July, 2006. It takes place in the remote wilderness of Alberta, Canada. Like David Wellington's other novels, it is set in a world similar to the real world, but where werewolves and other supernatural phenomena are rare but known and accepted phenomena.

The novel opens with Cheyenne "Chey" Clarke parachuting into the wilds of Alberta, provisioned with extensive hiking supplies, most of which are immediately lost. Chey is soon attacked by a werewolf. She survives with little more than a scratch, but it is enough to curse her with lycanthropy. While wandering through the wilderness, she meets the enigmatic Dzo, who introduces her to Monty Powell, presumably the werewolf that attacked her. After their meeting, it is revealed that Chey has secretly come looking for him, and is working with outside parties who want him removed.

The werewolves in Frostbite have only two forms: human and lupine. They cannot control the change, and take on lupine form at any time that the moon is above the horizon, regardless of the moon's phase. The lupine form is similar to a normal wolf, but significantly stronger and more aggressive, bearing an intense hatred of humans. They posses features similar to those of the dire wolf, including unusually wicked teeth. Even in human form, the werewolf is notably stronger, faster, and more resilient than a normal human of its physique would be. Werewolves in either form have only a hazy recollection of events in their other form. Though the lupine form hates its own human form just as much as, if not more than, other humans, there is some sort of slight mental connection, and the lupine form will often try to complete a task that the human form was engaged in when it changed. Still, some werewolves in human form are known to think of "their wolf" as a separate entity.

Unlike many interpretations of werewolves, one form does not "morph" into the other. Rather, the body becomes ephemeral and a new body is created at every change. As a result, werewolves seem to be unaging, as a new perfect body, healed of any and all injuries, is created for it at every moonrise and moonset. Werewolves are also apparently immortal, as a dead werewolf will always return to life with the next change, unless silver is employed to kill it. Indeed, silver is the werewolf's greatest weakness, as even a relatively light binding of silver chain cannot be broken by one. The effects of long-term contact with silver, or of silver weaponry, are not yet clear. It is known that contact with silver bindings in lupine form can leave a lasting mark when the werewolf regains human form.
