Goodnight, sleep tight-don't let the dragons bite. After Ambrose Beake's kidnapping two years ago, he's determined to return to normal life. A simple routine of running his potion shop, training his apprentice, daydreaming about his boyfriend Eli's pending proposal... (Eli tries to hide it. Ambrose knows he bought the ring months ago. )But when an angry dragon trapped beneath the city demands help through Ambrose's dreams, he realizes his adventure isn't yet finished. He quickly concocts a plan: shrink the dragon with a potion and smuggle it to safety before the city discovers its presence. To retrieve the needed ingredients, however, he must take a cue from his customers... and go on a quest himself. While Ambrose, Eli, and friends fumble through heroics abroad, his apprentice Nat takes control of the shop. Before long, she struggles to keep the dragon problem-and her feelings for another apprentice-under wraps. Magical merchants both near and far must pull themselves together... before the city goes on its own quest to slay the dragon.
