Donovan's Gambit

THREE HUNDRED YEARS AGO, THE HARVEST BEGAN WITH A SINGLE MISTAKE. They don't invade. They don't negotiate. They eat. Every world they've found with thinking, feeling, terrified things on it - consumed to the bone. No exceptions. No survivors. No mercy. Earth is next. Drake Donovan is a retired colonel fixing cell towers in rural Oregon. He has a wife, five kids, and absolutely no reason to believe he's humanity's last hope - until an intelligence forty thousand years more advanced than anything on Earth shows him exactly how this ends. He has no army. No plan. No government backing. No time. What he has is a forbidden program that reaches across the veil of time to place the greatest military minds in human history at his disposal. The cost of failure is extinction. The cost of success might be worse. A high-octane military science fiction thriller perfect for fans of The Lost Fleet, The Bobiverse, and Old Man's War.
