Emmy in the key of code

Twelve-year-old Emmy feels out of place in her new school. She takes a computer coding class and instantly connects to the material as well as to a new friend, Abigail--a talented singer who secretly wishes to be a coder--and Emmy feels she's finally starting to find her footing. Then she finds out that the teacher who so inspired her is gravely ill and her new-found stability seems to be at risk. Told through prose, verse, and Java code.
