Armstrong, Kelley - Women of Otherworld 04 - Industrial Magic

After Paige Winterbourne is ousted as leader of the American Coven of
Witches, all she wants to do is hide under her duvet for a few months.
Let the supernatural world manage without her, see if she cares... But
fate, of course, has other plans. A murderer is on the loose - someone
with superhuman skills. When Paige learns that the killer is targeting
children, she realises she has to get involved in the covert
investigation. And so Paige - desperate to protect those she loves - is
thrown into a world of arrogant Cabal leaders, drunken necromancers,
sulky druid gods and pretentious leather-clad vampires. Luckily, she has
a female werewolf and a certain renegade sorcerer on her side...
