Author Thomas A. Cahill of Davis will present a talk about his newest novel “Ark: Diaspora,” the second installment in his science fiction adventure “Ark Asteroid” trilogy, at 7:30 p.m. Saturday at The Avid Reader, 617 Second St. in downtown Davis.

It is the sequel to “Ark: Asteroid Impact,” published last December.

Picking up where that book left off, “Ark: Diaspora” returns readers to the battered coastal areas of Central and Northern California 4 1/2 years after the catastrophic collision of a large asteroid with the Earth. “Ark: Diaspora” details the continuing struggles, successes and perils of isolated groups of survivors following the colossal impact, which cracked and flexed the Earth’s crust, triggering tsunamis that leveled coastal areas and triggered volcanic eruptions throughout the world.

The lethal chemical cloak that choked the Earth precipitated a rapid-onset ice age that resulted in the extinction of nearly all forms of plant, animal and aquatic life on the planet.

In isolated outposts along the coast of California, colonies of refugees managed to survive but now find themselves the target of a nuclear missile strike by the Russian military.

In “Ark: Diaspora,” the Earth itself is the ark in which these disconsolate but determined colonists and their allies struggle not only for the survival of species on Earth, but also for the endurance of the human spirit.

Cahill is a professor of physics at UC Davis. His research focuses on two areas: the effect of aerosols on global climate change — including conducting an aerosol program on the Greenland ice cap for the National Science Foundation — and the impact of ultra-fine aerosols from highways and rail yards for the U.S. Environmental Protection Agency.

He is the author or co-author of hundreds of academic articles and book chapters. This is his third work of science fiction. His first novels, “Annals of the Omega Project — A Trilogy” and “Ark: Asteroid Impact,” were published in 2012 by EditPros LLC of Davis.
