Tropic of Creation

(From the author's website:) Captain Eli Dammond has landed on a deserted planet to rescue survivors of a crashed space ship. In his charge is Sascha, the fourteen-year-old granddaughter of a general. But the planet is about to undergo a radical seasonal change, one that will hatch terrifying creatures. There are few refuges from the rampaging season. One is deep underground where a bizarre civilization lies hidden. It's no place for a human army officer, as Eli will learn. The other – Sascha's only hope – is in the the nests of the monsters themselves.
