Thunderlane is a stallion's stallion, and he knows it. Unfortunately, this has created a lot of unstable relationships with the ponies he knows, and he keeps falling in and out of relationships because no pony he knows can meet his standards. He's about to break up with his current marefriend for reasons he's not even sure of, and is hesistant about getting into a relationship with another.

But Thunderlane's life is about to take an unusual twist. A signing event in Ponyville's new library leads him to meet with one of his favorite authors. But life is not so clearly marked out like the pages in Thunderlane's favorite books, and he's about to find out this strange stallion has a few tricks up his sleeves, tricks that will shake Thunderlane's foundations and quite possibly reveal a thing or two about himself he wasn't previously aware of.

That is, if Thunderlane can realize what he's doing to him.
