A potent, powerful and timely thriller about migrants, drug lords and gang warfare set on the US/Mexican border by PRINTZ MEDAL winning and CARNEGIE MEDAL, COSTA BOOK AWARD and GUARDIAN CHILDREN'S FICTION PRIZE shortlisted novelist, Marcus Sedgwick.

Anapra is one of the poorest neighbourhoods in the Mexican city of Juarez.

Twenty metres outside of town lies a fence, and beyond it, America - the dangerous goal of many a migrant.

Faustino is one of them, trying desperately to escape from the gang he's been working for. He's dipped into a pile of dollars he was supposed to be hiding, and now he's on the run.

He and his friend, Arturo, have only 36 hours to replace the missing money, or they're as good as dead.

Watching over them all the while is Saint Death. Santissima Muerte. She of pure bone and charcoal-black eye, she of absolute loyalty and neutral morality, holy patron to rich and poor, to prostitute and narco-lord, criminal and police-chief.

A folk saint, a rebel angel, a sinister guardian.
