The Phoenix in Blue

Equestria and its allies, including the newly reintroduced Crystal Kingdom, have pushed back their aggressors and won a short but brutal war against the extremist gryphon empire... but it has come at a price--Celestia, the divine, the unkillable, struck down in the dark by a toxin none save the gryphons even knew existed.

Now the responsibility of rebuilding and ruling Equestria falls straight onto Luna's back--or it would have. She has a more immediate problem in dealing with a power-hungry, dominating unicorn known as Trine, who has stolen her throne and locked her in her own dungeon. Now she has to get out and get even--but if she can't trust her own little ponies, who can she trust? And what about Trine's shifty second-in-command, singer-turned-swordfighter Sole Star?

Meanwhile, Canterlot is being blasted by a massive storm, and Blaze Bright thinks she knows who's behind it. She's going to put a stop to it, and so help her, Sole Star's sister Solemn is going to come along for the ride!
