The Dragonling: Dragon Quest (Book 3) by Jackie French Koller

In Book 3 of The Dragonling series, Darek and Zantor work together to stop the kidnapping of another baby dragon in this third book in the fantastical Dragonling chapter book series! Now that the villagers have finally accepted Darek's dragonling, Zantor, they've all fallen in love with him. Especially Rowena, the spoiled daughter of the Chief Elder—so much so that she wants the dragonling for her very own. But Darek can't give him up! He and Zantor are so close that he can almost get inside the little dragon's mind. So the Chief Elder orders Darek's father to find another dragonling. Even though a dragon mother will have to die—along with some villagers, too. Darek can't let that happen. But how can he stop them…unless he joins the dragon quest?
