Warstrider (Warstrider Series, Book One)

In the 26th century, humanity is at war with the Xenophobes, and the planet Loki is the next battleground. Dev Cameron joined the military to fly a starship, but is rated unsuitable and grudgingly accepts an assignment with the ground forces piloting a massive walking tank- a warstrider. But Cameron may yet get a chance at glory when he makes a discovery about their alien foes that could change the course of the war.

The first book in Ian Douglas's classic Warstrider military sci-fi series, originally published in 1993 under the name William Keith. The six-book Warstrider series is being re-issued by War Planet Press.
