If you'd had a LOT of chances to stop something from happening, how many would it take to get it right?
The Great & Powerful Trixie has gotten hold of a new spell that she believes will make her act even more great & powerful than it already is... however, it's not as it seems to be, as the spell is actually FAR more than Starlight Glimmer ever needed to know about perfecting the art of saving her best friend's flank from disaster.
Now, after waaaaaaaaaay too much experience, she simply has to make sure NOTHING goes wrong in her latest attempt to get the spell (and its' caster) under control... or the nightmare never ends.
