Midnight and the Sonic Rainbooms

Twilight Sparkle (nicknamed Sci-Twi) isn't exactly having the greatest week of her life. When her father passes unexpectedly, leaving her and her six sisters two inheritances. The first one is half of his music company, Canterlot Records. And the other is Golden Oaks, a home for foster girls, which Twilight and her siblings have spent all their life in. Only problem is that the building needs repairs and the other owner of Canterlot Records, Storm King, refuses to give Twilight the money she needs, and is instead spending said money on promoting a "hot" new band called The Dazzlings. But when Twilight and her sisters find out their father left each of them a special necklace, they'll discover something truly outrageous!
