Half of known space is littered with the skeletons of metal and bone from thirty years of war with the ahtra, humanity's implacable enemy. Now, Captain Eli Dammond has landed on a deserted planet to rescue survivors of a crashed space ship. On this routine mission, Eli has in his charge Sascha, the fourteen-year-old granddaughter of a general.
But the planet is not what it seems. It is about to undergo a radical seasonal change, one that will hatch monstrous, rapacious creatures. There are few refuges from the rampaging alternate season. One is in the secret ahtran habitat far underground. It's no place for a human army officer, as Eli will learn. The other is in the most unlikely of places: the nests of the monsters themselves. Not that the intrepid Sascha ever had a choice. As her time runs out, Eli must break free of his ahtran captors and return to the surface before his crew is wiped out and Sascha is forever changed.
