Mkoch Spottedleaf loves Firestar as much as Firestar loves her. Their love is complicated and almost impossible, but that is where Sandstorm comes in. Just so you know, I wouldn't east my time figuring out their love connection if I still had Warrior books to read, instead, I would be reading till I die of insanity or finish the series. ;-)
Sophie Moffitt Spotted leaf likes firestar like she likes the clan. Plus they could never have been mates.
