Breakthrough — Scott Washburn

The Battle for Earth continues! The merciless invaders from the Red Planet have entrenched themselves all over the world, but President Theodore Roosevelt and the men of the US Army and Navy are focused on the aliens threatening the American heartland. As forces are rushed to meet the invader, science and industry race to build the weapons needed to match the fantastic machines of the aliens. But not all is well with the Martians as they struggle to adapt to a new world. The lines are drawn as each side prepares for what they hope will be the decisive battle. This is the second book in the first trilogy of The Great Martian War.
