Firestorm (Starfist, Bk. 12)

Desperate to thwart unrelenting aliens and their quest to obliterate humankind, The Confederation has beefed up its defenses. But to the citizens on the outer edges of Human Space around Ravenette--unaware that a deadly enemy even exists--the government's move seems oppressive, and ten planets have responded with a war of secession.

In touch-and-go battles with the seceding planets, the 34th FIST has emerged battered but unbowed, refusing to give up . . . even while under the command of a fanatical general. The enemy determined to strike, a new mission must be carried out, though the troops will likely return in body bags.

Should Ensign Charlie Bass and his Marines somehow survive the nightmarishly difficult amphibious landing, they can expect to be outmanned, outgunned, and out-armored in a fierce duel against fresh soldiers. But like any Marine worth his salt, Bass knows there's only one way to go when facing impossible odds: on the offense with all guns firing. There's no other choice--because if life was easy, there'd be no need to send in the Marines.
