Murder in an exclusive gymnasium. Counterfeit pharmaceuticals. A kidnapped witness. The Sinaloa cartel again.

Phoenix Assistant DA Clara Alvera calls Detective Lori Sanchez in the middle of the night to report the gruesome murder of her friend-a reporter named Josie Vale. The reporter was onto a story about counterfeit prescription drugs and the powerful Maraxx Pharma Corporation. Sanchez vows to protect the only witness named Lolita, a young gymnast.

As Sanchez builds her case, she learns that members of a local gang are perpetrating murder and trafficking fake pharmaceuticals. The Sinaloa Cartel-Sanchez’s old nemesis-is deeply involved. But how? And why do dead bodies keep turning up to block her investigation?

Sanchez works with her old friend, Father Guillermo Montero, to unravel a complex criminal enterprise that is hidden under the desert. When the cartel kidnaps Lolita, Sanchez must solve the mystery and save her life.

She must enter the desert underworld.
