Emerald Knight

Hal Jordan has always lived without fear.
A test pilot with a reckless streak and nothing left to prove, Hal's life changes forever when a mysterious visitor from beyond the stars chooses him for something far greater than he could have imagined.
Now, armed with a power he barely understands, Hal is pulled into a world far beyond Earth-and into the ranks of the Green Lantern Corps.

Under the guidance of the legendary Sinestro, Hal begins to discover what it truly means to be a Green Lantern. But as strange events begin unfolding across the galaxy, the Corps finds itself facing a threat unlike anything it has encountered before.
With the fate of countless worlds hanging in the balance, Hal will have to learn what it means to have courage...
and what it means to use it.
