Maximiliano loves stories, especially the legend about a mythical gatekeeper who can guide brave travelers on a journey into tomorrow. If Max could see tomorrow, he would know if he’d make Santa Maria’s celebrated fútbol team and whether he’d ever meet his mother, who disappeared when he was a baby. So when Max uncovers a buried family secret — involving an underground network of guardians who lead people fleeing a neighboring country to safety — he decides to seek answers on his own. With a treasured compass, a mysterious stone rubbing, and the legend as his only guides, he sets out on a perilous quest to discover if he is true of heart and what the future holds.
