One year after her return to Equestria, Princess Luna prepares to take her place in the world.

Wishing to celebrate her sister's return to Equestria, Princess Celestia revives a competition long-forgotten to modern ponydom: a race over the kingdom's oldest road. Twilight Sparkle and her friends sign up to participate in what they think will be a fun diversion, but will their individual reasons for running breed cooperation or conflict?

Little Rainbow Dash is loyal to one pony and one pony only: herself. It's a simple system, and it gets her through the days. But that all changes one stormy summer afternoon at flight camp, when another pegasus blunders into her life--a pegasus with whom she shares nothing in common.

As fires from the dragon lands threaten the Everfree Forest, the Elements of Harmony must find a way to stop them. In particular, one pegasus uncovers a talent she never thought possible, and must reconcile it with her life's calling.
