Twelve year old siblings, Sage and Crew have lived at Greenhouse Academy, a prestigious private school
for students with extraordinary abilities, for as long as they can remember. Their parents’ identities have always been a mystery.
When the siblings and their friends find out that within six months the air in Alberta
will not be safe to breathe, they are determined to find out why and how to stop it.
As Sage and Crew delve deeper into the mystery they realize that the answers to
both the pollution and their lineages may be found within the walls of the academy.
