In the wake of a solar eclipse, a portal between our world and a paranormal realm opens—and a scientist’s life will never be the same—in this print edition collecting all three parts of the groundbreaking Eclipsed Evolution Audio Original serial, from the #1 New York Times bestselling author of the Hollows series.

This is an omnibus of the previously published novellas First Contact, Totality, and Emergence.

Dr. Renee Caisson knows there are worse things than an attractive man in uniform drafting her into a secret government project. But neither Renee’s linguistic expertise nor her own checkered past can prepare her for when Major Jackson reveals the truth: her new subjects are demonic-looking beings who call themselves “Neighbors”—refugees from a dying world who arrived during the nationwide solar eclipse.

The Neighbors’ technology is unlike anything Renee has ever encountered. At first, she dismisses an injury that inexplicably heals as “just one of those things.” And surely August, the most gregarious Neighbor, begins to speak English overnight because of the team linguist’s skills?

Not until August begins evolving in real time to withstand Earth’s brighter, drier atmosphere does she admit that the Neighbors’ “tech” feels less like science and more like magic—the same magic that brought them here in the first place, and the same they’re trying to rekindle with a mysterious labyrinth in order to return home and save their world.

At least, that’s what August claims they came for.

But as a startling revelation about the true relationship between the Neighbors and the Earth comes to light, throwing human society into an uproar, Renee must decide where her loyalties lie—even as she herself begins to evolve in thrilling and frightening ways.
