find out that they plan on sacrificing them to a giant, meat-eating bird, the Diatryma. After escaping, Dusk finds a new home for his fellow Chiropters, but it is on the other side of a savannah, which is home to many predators. While Dusk is scouting for a good place, he meets another creature that looks similar to himself; it calls itself a bat and tells Dusk that there are many others like them. The Soricids overwhelm and devour a Hyaenodon, and nearly kill Dusk, but he is rescued by Sylph. He and Sylph are attacked by Carnassial and his Hyaenodons once again, and take refuge in the skeleton of a large dinosaur. Through it, they find their way into an eerie cave, where Dusk and Sylph discover a nest of an unidentified meat-eating Saurian, along with a clutch of mostly unhatched eggs and the rotting carcasses of the parents. The Felids return and Carnassial's mate is attacked by a young dinosaur, the sibling of the eggs who'd hatched early. Carnassial fights to save his mate, but both are killed in the confrontation. The saurian chases Dusk out of the cave and attacks the Hyaenodon as the heroes flee. Eventually, Dusk leads the Chiropters to their new home, and the book ends with him leaving the colony and promising his sister to return if he dislikes life with bats.
