Howling Moon (Tales of the Sazi)
C.T. Adams, Cathy Clamp

He's a wolf… She's a jaguar…
 
Raphael is a former agent of the shape shifter secret police, forced into retirement after a very public scandal.  Now he's assigned to help the victim of a hideous crime -- a woman who has been attacked by a serial killer, and accidentally turned into a were-jaguar.
 
Worse yet, Catherine turns out to be Raphael’s fated mate.  But the serial killer is still on her trail, and perhaps even worse, Raphael’s pack wants her dead. 
 
Caught between destiny and duty…
 
Raphael must make his choice -- and, in doing so, perhaps lose his pack -- in this tale of obsession, revenge, lust, pack politics, and true love.
