It's Christmas Eve at the North Pole, and everything is perfectly organized... until Santa looks over his sleigh team and realizes one reindeer is missing!
Vixen, the stealthiest of the reindeer, has vanished without a trace!
But Pip, the newest-and smallest-North Pole P.I. (that's Principal Investigator!), sees a clue: a trail of faintly shimmering hoofprints leading away from the stable.
Pip follows the twinkling trail past the chaotic Toy Testing Department and through the festive Snowman Village. But when the mysterious tracks lead to the dimming Northern Lights, Pip realizes this is no ordinary mystery. Vixen hasn't run away-she's on a secret, quiet mission to gather unlikely supplies to mend the world's fading magic!
Join Pip as he solves the case of the vanishing reindeer and discovers that the greatest gifts aren't always in the sleigh, and some mysteries are meant to be solved with heart.
