When Haley falls off Wings during an event and loses to her rival Riley, she vows to practice continually to make sure it does not happen again.

While searching for a sleek, fast, and spirited pony to own, a young girl comes to realize that the "perfect" pony is actually very different.

Although she is sad that she has to give up the pony she has outgrown, Steph is soon distracted from her own problem when she meets Comet, a magical pony who needs her help to find his twin sister.

"The Pony Scouts are becoming better at riding with every lesson. But just when they think they've seen it all, a new horse arrives on Jill's farm--one who hasn't been ridden before! Taffy is a beautiful palomino pony that needs Jill's help. With a little patience and a lot of love, Jill and the Pony Scouts will make Taffy a member of the family."--Dust jacket.

The same day Marcie learns that she will have to wait longer for the pony she yearns for, she meets Comet, a magical pony who needs her help to find his twin sister.
