The moon colony built around Superwoman's Fortress of Solitude is under siege! Shape-shifting aliens have come to this place of peace in search of Lynari, a refugee from their homeworld. It's a bad move on the part of these intergalactic bad guys: if Kara Zor-El offers you sanctuary, there's no way she's going to let anyone get their monstrous hands on you. Let's just hope this gamble is worth it, because Lynari's secret-the one that got her in trouble in the first place-could mean bad news for everybody!
