The Ant-Lion is an African adventure story in which three English children are invited to a wildlife conservation ranch in Tanzania, where they befriend a Maasai boy. The four of them face hair-raising encounters with lions, elephants, snakes, buffaloes and bandits, as they seek to find valuable minerals that could save the ranch’s finances and prevent its closure.

1898, Tsavo River Kenya, the British Empire has employed 140 workers to build a railroad bridge. The bridge's construction comes to a violent halt when two maneless lions devour all 140 workers in a savage feeding frenzy that would make headlines—and history—all over the world. Caputo's Ghosts of Tsavo is a new quest for truth about the origins of these near-mythical animals and how they became predators of human flesh.
