   Summary

   Three Spartans have been sent to the ruins of New Mombasa on a mission, to extract a device the Covenant have uncovered, by any means necessary even if they all are to die. But for the soldiers of the Spartan-III programs Gamma Company this is what they trained for, prepared for all their lives. A suicide mission to deal as much damage as possible.

   Emma Shepard didn't ask to be brought back to life, didn't ask to work for a shadowy terrorist organization and she sure as hell didn't ask to be sent on a mission to stop an Alien species known as the collectors from abducting humans but if she doesn't do it, no one else will. Building her crew she is willing to do whatever it takes to get to the bottom of the abductions, why they are targeting humans, and finally stop them... at all costs.
