Manhattan is underwater, and a sickness called the Blight is raging through the section of town, called the Ward. Sixteen-year old Ren is a daredevil drag-racer, racing around the rooftops of the waterlogged city, and trolling the sections for hints of fresh water in order to make enough money to buy medication for her sick sister. During a race, Ren deviates from the course and finds a secret underground spring with healing properties. Soon she finds herself running for her life, as she strives to save her sister and cure the Ward of the Blight. By the end of the book, I found I was holding my breath, hoping Ren would survive. I can't wait until the next book comes out.
Set in a futuristic Manhattan after a catastrophic flood called the Wash Out, Ren must race against a conspiracy to find freshwater springs and a cure for the deadly disease that has stricken her sister and many others in the Ward.
