David Wellington, “Frostbite” published in serial online in July, 2006 and in print in 2009.
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 have elements 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
Silver is the nemesis of werewolves, 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.
