A Harper Jennings mystery

When Harper Jennings' staunchest rival at Cornell's archaeology department turns up on her doorstep, babbling about seeing a Pre-Columbian shape-shifter, Harper doesn't know what to think. But she can spot a great opportunity—Zina won a coveted post cataloguing a priceless collection of Pre-Columbian artifacts, and if Harper humours Zina, she'll be able to see them for herself. But then Zina is killed—and the more contact Harper has with the relics, the more her life starts going wrong. The artifacts can't really be cursed... can they?
