Were-Geeks Save Lake Wacka Wacka by Kathy Lyons

Paramedic and firefighter Bruce Collier became a werewolf to protect his family—and hopefully make amends for the way he treated his younger brother. His bitterness nearly turned him into the monster he thought his brother was… until he met Mr. Happy. Werewolf Laddin Holt—aka Mr. Happy—likes things organized as he makes them go boom. He’s Wulf, Inc’s explosive expert and the only one calming the turmoil inside Bruce. At least until they’re drawn into a conflict between two factions of fairies living around Lake Wacka Wacka. Bruce wants to take them out, Laddin has other ideas, and neither of them sees the real threat lurking behind the scenes—or how their love could be the answer to everybody’s problems.
