Why this must be read:

This story has everything I love in a fic, and it has it in spades--humor, affection, smut, fabulous characterization, and sharp, on-target dialogue. The author describes this fic as a comedy of errors, and it truly is. It makes me giggle every time I read it. It's also a very romantic story, in a Sheppard/McKay kind of way. It's so very them.

He clutched at John’s arm, nearly sending the precious laptop spiralling to the floor. “Oh my God, you’re a genius!”

John said, “I am?” thinking, Uh-oh.
