The distraught mother of a kidnap victim is taking advice from a 'psychic' and interfering in the police investigation. Will Diana prove that the psychic is a fake? Unfortunately, the psychic is not a fake, but a very wicked witch. Drums: Jennifer Talldeer, shaman, private investigator. Most of Jennie's work is regular PI stuff, but Nathan Begay brings her a problem she's never seen before. His Chickasaw girlfriend Caroline has attracted the attention of an angry Osage ghost. Thwarted in love while alive, the ghost has chosen Caroline to be his bride in death. Ghost in the Machine: Ellen McBridge: computer programmer extraordinaire, techno-shaman. The programmers and players of a new MMORPG find that the game's 'boss', a wendigo, is 'killing' everyone - even the programmers' characters with their god-like powers. Ellen discovers that the game has created a breach between the supernatural world and our own. This wendigo isn't a bit of code, it's the real thing...and it's on the brink of breaking out of the computers and into the world. Featuring the first new Diana Tregarde story in nearly twenty years, the first Jennie Talldeer story in more than fifteen years, and introducing a new heroine for the 21st century, Trio of Sorcery is an entertaining work by a bestselling fantasy writer.
