Radiant Hope thought she could save Sombra from himself. Instead, she lost everything.
Alone and hurting, Hope finds her way to Seaddle and tries to settle down into a quiet and obscure life where she can be left to her sorrow. That is, until she crosses paths with Starlight Glimmer, who realizes that Hope could be the key to setting her own dubious plans into motion. They may not like each other, but before either of them knows it, a series of events launches them on a perilous journey along the western coast of Equestria and they must depend upon each other to survive.
Enter a devotee of Starlight's who takes this whole "Equality" thing a little too seriously, a quack doctor with an ego the size of Manehatten, a wandering lunatic that's convinced he's Starswirl the Bearded, and a secret agent intent on protecting the princesses at all costs, and things get complicated rather quickly. Everypony has their own agenda and nothing is what it appears to be. Through it all, Hope and Starlight will be forced to take a hard look at their lives and the choices they've made. But if they can manage to make peace with their respective pasts, our heroines might just have a shot at that rarest of things; redemption.
(For Radiant Hope, this story diverges at the conclusion the Siege of the Crystal Empire arc (Issue 37). It diverges between The Cutie Map and The Cutie Re-Mark for Starlight Glimmer.)
