On a trip to the Silver Shoals, Marble meets Princess Luna, and discover she has far more in common with a millenia-old alicorn then she'd ever thought possible. They both like quiet, relaxing evening with lots of cuddles, and both have sisters that outshine them. Marble never thought she'd fall in love with a mare, much less a princess, but fate as a way of bringing ponies together.
