After nearly being mugged Twilight turns her considerable talent with magic towards self defense. When a fight with Luna goes farther that either of them wants it to, Twilight will need to find redemption in her new position as Luna's bodyguard and stop a conspiracy that wants to bring back a force more dangerous than either of them.

Friendships don't always last, time isn't always well-spent, and not everyone gets a happy ending. Everypony has their regrets, paths not taken, failures and lost loves. Sometimes, it's too late for second chances.

Luna's isolation and difficult reentry into Equestrian life has left her without the confidence to communicate with the ponies around her. Especially the one pony she most wants to talk to. Celestia is angry, Twilight is upset and it's all her fault. Then she has an idea... She'll invite Twilight into her dreams. What could possibly go wrong?

Twilight Sparkle and her fellow Elements of Harmony have faced down supernatural foes of the highest order, but sometimes the deadliest danger can come from places one would least expect. As Twilight is forced to bear a devastating secret, her efforts to keep the Elements together may well tear them all apart.
The plotline of the thrilling Pony Psychology Series continues with an exploration of deception, despair and Discord.
