To cope with everyday life, neurodivergent Kat is a secret binge drinker, and jilted Ryan is a workaholic. Disillusioned, neither does more than go through the motions of living—then comes the asteroid.

Warned that a planet-killing asteroid is on a collision course with Earth, acquaintances Kat and Ryan join forces in an effort to survive. Mere hours before impact, they race toward the safety of Ryan's inherited South Dakota bunker, encountering chaos. A last-ditch effort to nuke the asteroid only manages to fragment it into chunks causing multiple strikes.

Earthquakes, fire, and volcanic ashfall assail Kat and Ryan, who turn to each other for solace. Kat finds someone kind who values her differences and Ryan finds himself falling for Kat's pluck and quick-thinking. Though jaded, they learn to trust and rely on one another.

Attempting to survive the onslaught of their new world, Kat and Ryan must reach the bunker before imminent food shortages and catastrophic climate change cause society to further unravel.

The Edge of Life shows that survival can include falling in love. With steamy romance and non-stop action, this is one thrilling apocalypse road trip you shouldn't miss.
