Gust Front

As part of the Galactic Federation, human armies help battle the aggressive aliens known as the Posleen, meeting them in a catastrophic war on the planet Barwhon V. When the Posleen begin an invasion of Earth, however, the humans ignore the fact that the invaders outnumber them and wage an unorthodox and surprising form of warfare. Ringo's sequel to Hymn Before Battle displays the author's talent for combining fast-moving battle scenes with vignettes of individual courage and sacrifice. A good choice for most sf collections.
