The Unspoken by Heather Graham is a clever tie-in to the most recent title in the Krewe of Hunters series, The Unholy. Medical Examiner and paranormal investigator Kat Sokolov was involved in the investigation, featuring the possible reanimation of the mummy of Amun Mopat. Amun Mopat was supposedly an evil and powerful sorcerer during the reign of Ramses II. A ship carrying the contents of the tomb of Amun Mopat sank in Lake Michigan in 1898 and has never been found. A group of Egyptologists based in Chicago think that they have found it by tracking weather patterns and when a storm occurs they hope that it would have dislodged the ship. The leader of the expedition deviates from procedure and dives alone. He is found dead at the site of the ship which has indeed been found.

Kat Sokolov is not only an ME, she can see and talk to ghosts and is an experienced diver. When she arrives in Chicago she is teamed up with Will Chan, former stage illusionist and now FBI agent. Will and Kat's first meeting does not go so well as he appears to be somewhat arrogant and abrasive. Kat soon finds that he simply doesn't suffer fools gladly! Bodies keep piling up and Kat and Will are pressed to figure which out of many motives is the real one. Even though they both have paranormal abilities, they know that human beings, not ghosts, kill other human beings.

The Unspoken is very well-plotted with a nice supernatural atmosphere and vivid characters. It's a very enjoyable quick read.
