Time to drop

In royal woods, everyone expects a normal week.....or did they?
Earth, the u.n.s.c's deepest secret, the u.n.s.c's most prized jewel. They will stop at nothing just to keep Earth a secret from the Covenant.
The Covenant is a superior alien alliance with advanced technology at their disposal. They would easily destroy Earth using just one Covenant ship! The problem is, they have millions. For the years the Covenant has been terrorizing human beings by destroying human colonized planets. But what the Covenant doesn't know is that there is one more guarded secret. Earth.
