Path of the dead Arthur Nakai Mystery Series, Book 1

"The battle is one of wits and cunning, where the strong heart will overcome his enemy. Ex-marine Arthur Nakai spent years as a member of the Shadow Wolves, an ICE tactical unit tasked by the US government to hunt human traffickers and drug smugglers on the US/Mexico border. He put that life of confronting violence in the darker contours of the desert landscape behind him and settled into a quiet existence in New Mexico with his wife, Sharon, a local TV reporter. But when Sharon goes missing after crossing paths with a serial killer who has just added to his list of young victims, Arthur's calm world is shattered. He must return to the darkness of the life he left behind in order to save what matters most to him, and the future he and his wife plan to share together. He can only hope that she is still alive, and that his skills will be enough to find her. So begins the hunt -- to find a ruthless killer and save the love of his life."-- Amazon
