Love, aka deleria is the reason for all problems in the world, which is why upon every citizen’s eighteenth birthday, a cure is administered, severing the receiver from potential infection. Boys and girls under the age of eighteen, of course, are separated, lest interaction between two uncureds causes an infection. 17 year-old Lena Haloway, like all other teens her age, can’t wait to get the vaccine and be cured of the deleria - she hopes that becoming cured will finally sever her from the stigma of her uncured mother’s suicide. Just a few months before her scheduled cure, Lena meets Alex, somewhat by accident, and becomes infected. Headstrong and in love, Lena begins to question the cure, as well as everything her society stands for and has taught her; yet her cure date looms ever-closer, promising to destroy herself and Alex.
