Long ago, the great Snow Queen died of a broken heart, sending her magical world of dancing snow flakes and glittering icicles into a deep depression. Fearful of the same fate, her subjects sealed their hearts into an icy crystal for safekeeping, hoping to protect themselves and their future. For centuries, the communal Snowheart keeps the snow spirits of the north safe from their emotions, until a mischievous luck spirit steals the mystical crystal, intending to melt it down and extract its magical power at the cost of the snow spirits' lives.|
Marmion Roy never dreams of such a frosted, wondrous world until a snow spirit invades his reality, his home, and his heart. Shirai demands his help to recover the Snowheart and annihilate the thieving luck spirit. Because Shirai is void of softer emotion, Mar believes that love with a brusque and literally heartless spirit would be impossible — at least until Shirai accidentally is reunited with his own personal part of the Snowheart.
