War Dogs - La série

They made their presence on Earth known thirteen years ago. Providing technology and scientific insights far beyond what mankind was capable of. They became indispensable advisors and promised even more gifts that we just couldn't pass up. We called them Gurus. It took them a while to drop the other shoe. You can see why, looking back. It was a very big shoe, completely slathered in crap. They had been hounded by mortal enemies from sun to sun, planet to planet, and were now stretched thin -- and they needed our help. And so our first bill came due. Skyrines like me were volunteered to pay the price. As always. These enemies were already inside our solar system and were moving to establish a beachhead, but not on Earth. On Mars.

A new planet. A new battle. Same war. After barely surviving his last tour on Mars, Master Sergeant Michael Venn finds himself back on earth in enforced isolation. Through a dangerous series of operations he returns to Mars to further his investigation into the Drifters -- ancient artifacts suddenly reawakened on the red planet. But another front in the war leads his team to make the difficult journey to Saturn's moon, Titan. Here, in the cauldron of war, hides new truths about the Drifters, the origin of life in our solar system and the plans of the supposedly benevolent Gurus, who have been "sponsoring" and supporting humanity in their fight against outside invaders. Killing Titan is the second book in the epic interstellar War Dogs trilogy from master of science fiction, Greg Bear.

Marooned beneath the icy, waxy crust of Saturn's moon, Titan, Skyrine Michael Venn and his comrades face double danger from Earth and from the Antagonists, both intent on wiping out their growing awareness of what the helpful alien Gurus are really doing in our solar system. Haunted by their dead and by the ancient archives of our Bug ancestors, the former combatants must now team up with their enemies, forget their indoctrination and their training, and journey far beyond Pluto to the fabled Planet X, the Antagonists' home world, a Sun-Planet in the comet-generating Kuiper belt. It's here that Master Sergeant Venn will finally understand his destiny and the destiny of every intelligent being in the solar system-including the enigmatic Gurus.
