Can love defeat the laws of physics? Science teacher Alex Kavanagh's love life is imploding, his job repels him, and there's friction with the teenagers who bully him at the bus stop. Even his super-power - being pedantic - doesn't help much. Enter his ex, Lucy, in what seems to be a chance meeting. Her betrayal marked the point when his life went nuclear. But - holy protons! - he still loves her. Two problems. First, she isn't who he thinks she is. Second, she's going to leave him forever in seventy-two hours. An intelligent and deceptive love story about a nerd searching for his theoretical Big Bang.
