A Student of Living Things – Susan Richards Shreve

Even in the confusion and dread of the post-9/11 world, the tightly knit Frayn family is fairly well insulated from the snipers, bomb threats, and natural disasters that plague Washington, D.C., a few years into the future.

Then, in the moment it takes Claire Frayn to dig for her umbrella while her brother Steven waits next to her on the library steps of their university, he is shot and killed. Shattered, the family scatters to whatever havens they can find. Steven’s father moves into the airplane hangar behind the house, his mother moves into the glass factory where she works, and Claire, a biology student, adapts.

Galvanized by an impassioned stranger who claims to be her brother’s friend, she sheds her measured academic persona and sets out to avenge her brother’s death. Expecting to uncover a political conspiracy aimed at her outspoken brother, Claire finds instead her family’s own darkest secrets and her true love.
