The Green Moon

Luna Loud has been chosen as a new green lantern, Green Moon. Although
she keeps her identity a secret from most of her family, Luan being the only exception, she largely feels undeserving of the power of a Green Lantern. Due to the loss of a part of her family, all because of a plan to get back at him taken too far and stopped too late.

But when a Red Lantern arrives and loses his life on Earth, his ring ends up bringing back that lost part of her family, only now he's a rampaging blood puking pissed off version of himself. Will Luna be able to get back what she lost, or will she loss him again.
