Dan, the Boy Flyer, returns to the Age of Discovery—this time joining Admiral Columbus on his second voyage to the New World. As Miguel, a young page aboard the flagship, he quickly discovers that the challenges of this journey go beyond treacherous seas.

A jealous sailor named Pedro, who sailed with Columbus before, grows resentful of Miguel's rising influence and courage. When Pedro's envy turns to sabotage, Miguel must outwit danger not only from the wild shores of the Caribbean but from within his own crew.

As Columbus builds a new fort, tensions erupt with native tribes, and Dan finds himself in the middle of uneasy alliances and brutal clashes. Meanwhile, a mutinous commander, Alfonso, tries to silence Miguel permanently. But when Alfonso's plot is exposed, his followers turn away in shame.

Even as Columbus struggles to maintain peace and order, powerful enemies like Bernal de Pisa conspire against him back in Spain. Can Dan help Columbus hold the colony together and protect the future of the New World?
