Shamrock Day is an important celebration for the Mareish ponies, an yearly celebration of family and friends, and Lyra Heartstring's favorite day of the year. This year, she'll be bringing her wife and daughter, Bon Bon and Tootsie Flute, up to Mareland for the celebration.

But everything is not turning up roses in Mareland. Lyra's family has crossed paths with an upcoming band of thieves, who are extorting money from the townsponies and evading the City Guards at every turn. Her Mareish fighting blood ignited, Lyra becomes determined to put the criminals in their place.

Meanwhile, Phillip Finder follows a different trail to Mareland. Their paths will cross on the foggy moors, where the luck of the Mareish might just run out...
