Secret Invasion

"Nova has received an emergency call from a planet in peril -- but how do you save a world being devoured by a force of nature? When you're the galaxy's lone space cop, is there any way to stop the planet-consuming Galactus from feasting, or do you instead try to save as many refugees as possible? And do you reach out to your former ally, the Silver Surfer -- who is once again feared Herald? Whatever Nova decides, nothing will prepare him -- or you -- for the horror know as Harrow!"--Cover.
