The Dragon of Trelian — Michelle Knudsen

Calen, a lonely young mage-to-be, never dreamed that Princess Meglynne would become his friend. And impulsive Meg never imagined that tending a baby dragon would link her to the creature -- for life. And now Meg's sister is about to marry a prince to end a war between kingdoms, a celebration that Meg and Calen know is endangered by a murderous plot. How can a girl, a boy, and a dragon merge their magic and strength to bring down a powerful traitor in time? From the author of Library Lion comes a classic middle-grade fantasy soaring with sorcery and suspense, spunk and adventure, friendship and first romance, and a cast of enchanting characters.
