Izzy's Lucky Clover

(Originally published on FiMFiction.) Izzy takes it upon herself to cheer up Sprout and make him feel welcome and wanted again. Sprout isn't in the mood, still distrustful of pegasi and unicorns. But Izzy isn't the type of pony who takes "No" for an answer. Will she be able to break through to Sprout and win his affection? Or is Sprout simply incapable of loving a unicorn?
