Book excerpt: To fight a war, the world needs a new kind of warrior. In 2050, after sending disturbing distress calls, one of Earth's research outputs on Mars is cloaked in ominous silence. The U.S. military wants answers, and only its bravest commandos can get them. Navy SEALs are the best on Earth; now a select few are being sent to the stars with a new moniker: SEALS (Sea, Air, Land, and Space). The direness of the Martian situation becomes apparent when Lieutenant Thomas Stonewall Jackson and his men are kidnapped by hostile aliens. Now they may have to steal an alien aircraft, fight through several battalions, and even take out a highly advanced planetary defense system or two. But what's impossible for most is just another op for this twelve-man team, the best warriors in the galaxy.
