A propulsive, urgent thriller about Lydia and her young son Luca, who flee Acapulco after a cartel massacre kills the rest of their family. What follows is a breathless journey northward toward the US border — hiding in freight trains, navigating coyotes and checkpoints — as Lydia slowly realises that the cartel boss hunting them is someone she thought she knew.

A quick, compulsive read and a real page-turner. Cummins writes the violence and desperation with real energy, and the mother-son dynamic gives it emotional grounding.
