Life is good for eighteen-year-old Franklin. He lives on the spectrum, structuring and organizing his days, avoiding messy situations and ambiguity. But what he really wants is a boyfriend.

Twenty-one-year-old Patrick has a past he can't seem to shake, and a sexual identity that's hard to describe—or maybe it's just evolving.

When a manmade virus sweeps the globe, killing nearly everyone, the two young men find themselves thrust together, dependent on each other for survival. As they begin to rebuild their world, their feelings for each other deepen. But Franklin needs definition and clarity, and Patrick's identity as asexual—or demisexual, or grey ace?—isn't helping.

These two men will need to look beyond their labels if they are going to find love at the end of the world.
