Ok...here's my stab at a summary without giving too much away:
Eli James has a problem: he dreams. In a society dominated by logic and intelligence, he sets out to find a cure for this anomaly before it dismantle a promising future for the young analyst.
His research brings him into contact with a girl named Zepher, who defies reason with every encounter. Her fierce nature and odd ways begin to pull at the threads of Eli's carefully ordered life, revealing a terrible secret about not only his past, but the history of their entire city.
This story explores the relationship between a boy and a girl, emotion and logic, urban and rural, and the frail balance that exists between them all.
