Summary from GoodReads:
"Nineteen-year-old Nayeli works at a taco shop in the remote Mexican village of Tres Camarones and dreams about her father, who left for America years ago. Recently, it has dawned on Nayeli that he isn't the only man who has abandoned Tres Camarones. In fact, there are almost no men remaining - they've all gone north. This has also been noticed by a group of particularly nasty drug dealers, who, seeing an easy opportunity, plan to take over the town." But at a showing of the movie The Magnificent Seven at the village's decrepit theater, Nayeli has a vision: she will go north and recruit a group of men to return to the village. She will bring back her own "Siete Magnificos" to protect - and repopulate - her home. She and her friends head out for America, gathering a wild group of allies for a journey into the strange and beautiful land of their dreams and fears, the mythical place into which their fathers vanished, Their destination: a small town in Illinois, where Nayeli hopes to discover her father, her warriors, and - if she's lucky - her destiny.
