“Wallace’s unsettling, mind-bending apocalyptic novel chillingly dives into what happens when the balance of the world is disrupted and an invasive species grabs the reins. Terrifying and, yes, poetic, this is a novel that gets under your skin with an 'it could happen here' kind of chilling grace.”
—Caroline Leavitt, New York Times bestselling author of Pictures of You and Is This Tomorrow

“Invasive Species cost me a perfectly good night’s sleep… I hope Wallace carries a screenplay of Invasive Species in his hip pocket; he’s going to need it.”
—Bill Ransom, author of Jaguar

“If Wells’s Martians scared you, or the Body Snatchers, or the Alien films, you might want to read this one under the bed. Brilliant.”
—Jack McDevitt, Nebula Award-winning author of Starhawk

“Joseph Wallace re-births an ancient terror with creepy, pulse-pounding plausibility. His tale is just a few mutations away from coming true.”—David Brin, author of Existence
