The Summoner- Layton Green
"A United States diplomat disappears in front of hundreds of onlookers while attending a religious ceremony in the bushveld of Zimbabwe.
Dominic Grey, Diplomatic Security special agent, product of a violent childhood and a worn passport, is assigned to investigate. Aiding the investigation is Professor Viktor Radek, religious phenomenologist and expert on cults, and Nya Mashumba, the local government liaison.
What Grey uncovers is a terrifying cult older than Western civilization, the harsh underbelly of a country in despair, a priest seemingly able to perform impossibilities, and the identity of the newest target."
Average to have a 4.5 rating average after 90+ reviews and a quick look at the writing indicates appears fine.
