Burning Water — Mercedes Lackey

Something ancient and incredibly powerful is stalking Dallas. First it attacked cattle, now it's going after people: men, women, even children-dozens at a time. And it leaves behind an aura of supernatural evil.

Detective Mark Valdez feels that evil. He's dealt with magic before, and he knows he's in over his head. So he calls in a specialist.

Diana Tregarde. Romance novelist. Investigator of unnatural events. Practicing witch. If anyone can determine what malevolent power is loose in Dallas, she can.

Power calls to power. Will Diana be an avenging angel or a willing sacrifice?
