The Dwarons Versus the World by Grant, vendu Paul B. F. NEUF

Dwarons are a weaker, smaller variety of dragons who thousands of years ago were rejected and exiled by the fiercer, more powerful dragons.

In this fourth book of the Dwaron series, the life of the youngest Dwaron, Dove, is still under threat as a result of her once having been kidnapped by evil humans. Her only hope lies with her brave twin brother Macaw, Cassowary the smartest Dwaron, and Penguin (who had inherited her father Magpies amazing eyesight). They all fly to the world outside their secluded island home of Divinia in a courageous attempt to find what is needed to save her.
