Rose and Ivy were in a car accident and Rose survived. Ivy ended up nearly brain dead and kept alive with ventilators -- not quite dead and not quite alive. In the months after the accident, Rose tries to piece together her life, but all she can find is a textbook about wars, a series of boys who she tries to use to take her pain away, and an older man who has also suffered loss, and teaches her to drive.
Beautifully written, but largely pointless. My synopsis does more credit to the plot than it deserves as this is largely an exercise is writing pretty prose, not really in telling a story. Be prepared to snoooooooooooooooze.
