The Last Twilight is part of the "Dirk & Steele" series by Marjorie M. Liu about a detective agency staffed by shapeshifters. In this entry, Amiri, the shapeshifter cheetah, is sent to Congo to protect a doctor, Rikki Kinn. Rikki is one of the world's best virus hunters and has rushed to a scene that is apparently an ebola attack. Once there, Rikki realizes that there is something else going on. When she is rescued by Amiri and his colleague, Eddie, it starts a game of hide-and-seek though the jungle of Congo. Their enemies are varied, and they have to contend with injury, memories, and fear of contamination from the mystery virus.

The plot of The Last Twilight is quite complex, with several 'baddies' - some of whom turn out not to be baddies at all. The cast of characters is fairly wide, including several different shapeshifters, but it's always possible to keep track of who is what. The highlights of the book for me are the setting in Congo and the complexity of the plot as Rikki tries to find out why so many people want to capture her. It is a good read, but perhaps overly complex in places for comfortable reading.
