Deadly descendant

"As a living descendant or Artemis the Huntress, private investigator Nikki Glass knows how to track someone down. But when an Oracle shows up, warning the Descendants about wild dog attacks in Washington, D.C., Nikki is afraid it might be a trap. The Olympians believe the "dogs" are really jackals, controlled by blood-crazed descendant of the Egyptian death-god Anubis. Whatever ... If Nikki hopes to muzzle Dogboy she's got to catch him in the act. But when she stakes out a local cemetery, she ends up face-to-snout with a snarling pack of shadow-jackals whose bite is worse than their bark. These hellhounds are deadly--even for an immortal like Nikki. "Dog" spelled backward may be "god" but that won't stop Nikki from teaching these old gods some new tricks. Like playing dead."
