Sacred Ground
by Mercedes Lackey
Jennifer Talldeer, is a private investigator. She is also Kestral-Hunts-Alone, an apprentice shaman learning modified tribal magic from her grandfather. She is called in to investigate possible sabotage at a local construction site where Indian artifacts have been found. Initially a run-of-the-mill investigation, it quickly spirals into a mess involving an old flame, Medicine and Native spirits running amok and an ancient evil once defeated by Jennifer's ancestor that has come back seeking revenge.
