We, the Vargas Ramírez family, come from a faraway place north of Tenochtitlan called Iztapalapa, Land of Clay Upon Water. A land surrounded by cars and dry grass; a place where the pieces of our small world were scattered. For some time we lived there, but then one day my father heard a beautiful birdsong that rose up and appeared to say tihui, tihui, tihui: let's go, let's go, let's go. And so we gathered up our friends who made up that small world and decided to head north, for the other side, and a better life.

Together the Boy and his family will journey from the Land of the Frogs to The Place Where Feet Cry to the River Where the Waters Tangle, fleeing Gunmen and braving Coyotes and plunging darknesses as black as an obsidian forest. Originally published in Mexico, Pilgrim Codex (Códice peregrino) captures through the eyes of a child one family's part in the ever-changing and fleeting story of the brave migrant warriors who search for a better place to live.
