Starlight in your eyes of blue (фемслэш)

When Kara Zor-El falls to earth, it's to a world only recently aware of the existence of aliens - and of magic. This changes what might have been, causing some people in relationships to realise that they're not soulmates. Eliza Danvers was a loving wife, but when her husband left to marry his soulmate, she became a bitter woman who despises soulmarks. Kara is left entirely in the care of Alex Danvers, Eliza's daughter. Until Alex's 18th birthday comes round, and with it her soulmark. What will happen when Eliza realises that Alex and Kara are soulmates?
