Halo: Helljumper #1

When the colony planet Ariel sends out a mysterious distress signal, it's up to the UNSC's elite, highly skilled special-ops Marines - the Orbital Drop Shock Troopers from the 105th - to find out what's happening. Also known as ODSTs or \"Helljumpers,\" these soldiers are some of the toughest in the galaxy.. and some of the roughest as well. As they descend onto Ariel, into an unknown world against an unknown enemy, two Helljumpers will find themselves at the center of an ancient mystery, and before it's solved, they'll have to put their friendship-and their lives-on the line.
