Cal, Letty, Tony, Opi, and Sasha were thrust together when they were kidnapped by the Molethian civilization and forced to become a fighter crew to battle against The Horde, the most vicious, predatory enemy in all the Milky Way galaxy. At first, only Letty could get along with the rest of them, and they basically hated each other. However, due largely to Letty’s efforts, they became not only the top fighting crew in the Shadow Warriors, but also a close family that love and support each other. Due to Opi’s amazing strategic thinking, Letty’s organizational skills, Sasha’s unparalleled ability as a weapons officer, Tony’s crack talent as a navigator, and Cal’s icy nerve as a battle leader, they have found a way to defeat two major Horde invasions.
Opi, already becoming the chief strategist for an entire wing of the Molethian space forces, decides that an entirely new way of fighting Horde forces must be put in place. Her audacious plan is to search a central volume of the Milky Way through which The Horde always travels, discover the military bases they have no doubt established, and destroy them all. She is convinced that a huge base has been built by The Horde on the opposite side of the galaxy, very near The Horde’s own small galactic home, the Dwarf Spheroidal Sagittarius Galaxy.
In the meantime, a third Horde invasion of about 40,000 ships nears Molethan’s home planet. Using Opi’s old strategies, Molethian forces manage to destroy it, but the new, highly capable Horde fighters make this victory far more difficult. In addition, Tony is reported missing and presumed lost. Grieving over Tony, whom she loved, Opi refuses to succumb to her grief, immediately commissioning the search for the other Horde home bases in the Milky Way.
A search party finds the monstrous Horde base almost 70,000 light years across the galaxy. Molethan appeals to the other Alliance systems, and a major attack on the base is started, with Cal the attack leader. Things seem to be going well when suddenly, in the midst of the battle, a new enemy strikes, heavily damaging not only Shadow Warriors fighters but also many of the Alliance carriers. The fate of the battle hangs on a razor’s edge. Can the Alliance, led by Cal, Opi, and the rest of their team, manage to win over two opponents, or are they destined to be destroyed by the combined forces of two enemies?
