But otherwise, she usually gets along better with dragons than people. One day, Zuli’s sea serpent, Rainbow, and the other sea serpents become sick with the drizzles, a condition that causes their magic to go haywire. Zuli manages to discover the cause of the sickness and a cure for the disease. However, she needs help to cure all the sick dragons. Will Zuli convince her fellow students to help before a powerful storm forces the school to close?
