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!
