Twilight hasn't emerged from her library in over two weeks, and Applejack has had enough. The only thing stopping her from bucking the door down is Rarity - the two friends once again at the opposite ends of an argument.

When events quickly change and escalate beyond all expectations however, and Applejack finds herself needing the others more than ever, it is Rarity who steps up to the the vast chasm that comes between them and Rarity who reaches for the other side.

But time is unkind, and Applejack does not have forever. The events that unfold around her will force her to the very edge, but when she falls into the unknown, who will be there to catch her? Will Rarity and the others reach her in time, or will she be forced to bet everything on an even greater risk just to survive?
