Ride along with the Time Explorers in their third adventure!

The third volume in the Terra Tempo graphic novel series starts off with a big bang as the series' intrepid heroes, Jenna, Caleb, and Ari race from the Cenozoic era to the modern age, making their way through the evolution of mammals. They will finally earn their degrees from the Academy of Planetary Evolution and be considered full-fledged Time Explorers. But when the Bone Wars of the late 1800s threaten to break over to the modern age, and Ari has been taken in for questioning, the kids find themselves in a fight alongside some of history's most notable natural historians, including Herman Melville, Annie Montague Alexander, and Andrew Carnegie. They must race to ensure the safety of the world's history—and its future.
