Felipe K'icab doesn't know who he is. He only knows he was born different than his human family, and he can't relax unless he's blasting reggaeton in his cab weaving through the streets of Guatemala City. The jaguar mask and his other human faces keep him safe--until El Bufo, a corrupt ex-cop, commandeers his cab and drags Felipe into a murder conspiracy investigation, trying to expose the foreign-backed regime's ecocidal and genocidal past.

Cristina Ramos knows who her mother's killers are. After witnessing the murder in a vision, she struggles to keep her grieving family from falling apart. When El Bufo's relentless vendetta throws Felipe into her life amid increasing civil unrest, Felipe and Cristina must overcome generations of institutionalized silence, uncover the secrets of their powers, and forge a path to justice, or else be swept away by another wave of violence.
