"Mills has a knack for creating plausible save-the-world scenarios..."
— Entertainment Weekly B+

"Darkness Falls keeps readers’ hearts pounding until the final pages and beyond. Mills writes with knowledge and authority, and while the novel is a work of fiction, it leaves you uneasy about the possibilities of its premise."
— Mystery Scene Magazine

"A fast-paced, heady thriller with a Doomsday scenario straight off today's front pages."
— Andrew Gross, New York Times best-selling author The Blue Zone & The Dark Tide

"Kyle Mills is a master of the page-turner . . . he will keep you reading well into the night."
— Vince Flynn, author of Memorial Day

"Masterful thriller writer Mills returns to his series hero, former FBI agent Mark Beamon (last seen in 2002's Sphere of Influence), with a pulse-pounding apocalyptic scenario that is terrifying in its plausibility . . . While such plots are a dime a dozen, Mills's meticulous research, pacing and carefully developed characters make this variation particularly convincing." 
— Publishers Weekly (starred review)

"Beamon, who's been featured in other Mills thrillers, is a seen-it-all character who hasn't seen anything like this . . . Mills has done it again: another up-all-night read (with nightmares to follow)."  
— Booklist (starred review)
