"Oh come on, Applejack! Just one trip around the clouds! One!"

It's an invitation that Applejack has heard countless times. However, no matter how often Rainbow Dash bugs her to experience an air ride, the farm filly flat out refuses.

Then one afternoon, on a day when Applejack is strangely quiet and distant, she suddenly agrees to Rainbow Dash's persistent request. The pegasus happily oblidges, not knowing what has truly motivated Applejack to give in, nor the fact that--more than anything--Applejack could really use a good friend right about now.

Twilight has always had feelings for Celestia. But whether these feelings are for her surrogate mother or for her imagined lover, nopony knows. It will take something strange to make her understand just what she thinks of the Princess; something like her conscience becoming sentient.

In which I, Twilight Sparkle, (the biggest idiot in Equestria), fail miserably, utterly, and conclusively in my valiant endeavor to keep my decidedly-more-than-Friendship feelings hidden from one Rainbow Dash (the sexiest fastest mare in Equestria).

When Ruby boards the first trans-oceanic flight in Equestrian history, the last place she expects to end up is stranded in the middle of Eternity's Crossing in the wake of a horrific zeppelin crash. After a mysterious tower leads her and a fellow survivor to discover a twisted and fragmented city twenty thousand feet below the surface of the ocean, though, a bit of fire and smoke is the last thing she needs to worry about. Between the horrendously disfigured residents and the paranoia of the madmare who once built and controlled it, daily survival in this corrupted utopia is anything but a guarantee. But with the help of some new friends and a few genetic enhancements, Ruby isn't going down without a fight, and in the process might just discover that the deadliest weapon in Harmony is herself.
