Kevin Anderson-A Forest Of Stars

Five years have passed since humans set fire to the gas-giant planets, unwittingly committing genocide of the Hydrogues-an infinitely powerful species of aliens-and igniting a war of epic proportions. Meanwhile, as humans struggle to fight against increasing hostilities from the Hydrogues, they learn from the Worldforest that they have awakened an ancient, fearsome, and merciless enemy in the Hydrogues. And when the water-based Wentals and the sun-dwelling Faeros are found, will humans finally have the allies they need? Or will they be caught in the middle of a war that could break apart the galaxy.
