Crucible

It began with Crossfire: a far-future novel of planetary colonization and alien first contact. Jake Holman, a man trying to escape a dark past, brought together a diverse group of thousands to settle on a new world. But instead the humans found themselves caught in the crossfire of a galaxy-spanning war between two disparate species: aggressive, militaristic humanoids known as Furs and passive, plantlike creatures known as Vines. Having cast their lots with the peaceful Vines, humanity faces all-out war against the technologically superior Furs. Our only hope? A virus designed by the Vines to remove all aggressiveness from the Furs. Can it spread fast enough to save not only Holman's colony, but the rest of humanity? And at what price to the Furs?
