Rainbow Dash is dead.

Scootaloo saw it herself; an aerial stunt went horribly wrong and her adoptive big sister perished in front of her eyes. She grieved, and her friends - including the late Rainbow's friends - did their best to comfort her. Although, she did notice that Twilight seemed to react to the news... differently from the rest. She seemed to act as if nothing was wrong at all, like Rainbow was even still alive.

Time passes. One day Scootaloo receives a strange book, one that tears open her still-raw wounds and threatens to shatter her mind. Can the Cutie Mark Crusaders solve the mysteries behind the book, and make the pilgrimage to the place where the dead are given new life? Will they discover the truth behind Rainbow's ultimate fate?

More importantly... will they survive long enough to tell the tale?
