The Remarkable Worlds of Phineas B. Fuddle #3

Angus and McKee, the time-traveling duo, find themselves in a radically altered India of the past, where the city-dwelling warrior King Ashoka and his enormous Dreadnaughts battle the Todas, who devote their lives to maintain the green of the forest. Our heroes must navigate through this war-torn arena in order to pursue Prof. Fuddle in the Hidden City of the Sixth Dalai Lama, so they can stop the timeline from changing before it's too late!
