Stilettos and Gunpowder. Gemma Stone, #3

My name is Gemma Stone. I'm a Maricopa County Sheriff's Deputy and not only must I deal with the sweat-soaked misery of the Arizona desert, I get to respond to a bunch of crazy 9-1-1 calls all day long. Like a parakeet up a tree, or a car accident where a tractor trailer full of fireworks is hit and the 4th of July comes a bit early. But some days crime takes a deadly turn. Police cars are suddenly blowing up.
Detective Sergeant Dante Delgado, the love of my life, was assigned to track down and stop the bomber. Am I worried? You betcha. There's a madman on the loose and he is very, very good at making bombs. Just when I thought things couldn't get any worse, the Feds think I'm in cahoots with an Iraqi warlord who deals in stolen antiquities. Ichabod, my murderous ex-dance partner, escapes from prison and I'm suddenly in everyone's crosshairs.
