"The Emerald Empress has had a vision. Sometime in the future, her greatest tragedy will come as a result of a battle with Supergirl...and she won't allow that to happen. Now she's manipulated Magog, Soloman Grundy, the sorceress Selena and the android indigo into joining her as the Fatal Five, and they're going to make sure that Supergirl's future stops dead in its tracks."-- Provided by publisher.
