Meet Nyx. This half-human, half-Drow private eye investigates paranormal crimes by day and is an elite Tracker of demons by night. She prefers working solo—and playing rough. So when a terrifying force starts murdering innocent humans and paranorms, and leaving strange demonic symbols burned into their buildings, it's a case Nyx takes very personally...

Meanwhile, Nyx's fellow Trackers are being killed one by one—and a sexy new Tracker named Torin is shadowing her every move. Torin has powers Nyx can't read, and sometimes she wonders whose side he's on. Nyx's instincts tell her something's brewing in the city's meanest supernatural streets, and that it's ready to unleash hell on Earth. Who can she trust? Now it's five minutes to permanent midnight...and Nyx's last chance means risking everything—even her own life.
