Seadrake (Dragon Mage Chronicles Book II‪)‬

After much deliberation, Andrei chooses to bring his inexperienced and highly unusual apprentice to the far-off island of Sutan-lei, where the eminent mage-scholar Master Luth is rumored to abide. It is Andrei's hope that Master Luth will have answers to the growing mystery he and Jander began to uncover in the city of Tempest as well as help his apprentice gain some degree of mastery over his unique--and highly unpredictable--prowess in the magic. But even as they struggle to piece together the puzzle in front of them, their enemy is close behind them every step of the way...and he is determined not to let the two of them get in his way.
