Green Lantern. The Brightest Day

Hal Jordan, the Green Lantern from Earth, has a mission - to protect the Universe from any threats, including hostile Corps that seek to turn the power of the Emotional Spectrum against the Green Lanterns. But at the end of the War of Light, at the dawn of a new Brightest Day, Hal faces a new vital task: to protect the Entities, embodiments of the colors of the Emotional Spectrum, from an unknown assailant who is enslaving them. While the Entities run amok on Earth, Hal has no choice: he must forge an alliance not only with old friends like Star Sapphire and Saint Walker but also with Atrocitus, Larfleeze, and even with his arch-nemesis - Sinestro.
This alliance puts Hal outside the law and endangers the lives of those he cares about. However, it may be the only way to save the Universe from the oldest and most dangerous enemy of the Lanterns.
