Bursting from the pages of BRIGHTEST DAY comes an all-new team-up of the Justice League of America and the Justice Society of America!
The return of the hero called Jade in the pages of BLACKEST NIGHT heralds the release of the powerful Starheart that empowers her father, Green Lantern Alan Scott. Now this chaotic force is unleashed on Earth, causing magic to go wild – and new metahumans to emerge!
