Sean O'Donnell

A werewolf, and Jim Hickey's best friend. O'Donnell is considerably younger than Hickey, and with slightly different abilities. He's a "blood brother" as a result of events in Kate Paulk's Vampire Con series, which means they have a kind of bond produced by O'Donnell donating some of his blood to Hickey to feed when he was weakened after an attack.

Appears in The Bounty Game, book 14, though the events depicted occurred during A Very UnCONventional Christmas, book 3.
