I come bearing a fic rec. This tale explores (and undercuts) the concept of soulmates - what is a soul? what is time? where do we go once we're gone? - and brings forth one of my favorite hallmarks of Buffy and Spike's connection - bad timing. How many times have we wondered "if only" for Buffy and Spike? So many times.
Within you'll find strong characterization, wonderful style, and a heartbreaking conclusion. Buffy and Spike's journey spans centuries and dimensions all within 3400 words. Every section of this non-chronological tale is honed to its finest and sharpest edge, leaving you with perfectly measured doses of angst and wonder.
Do not pass GO before you read A Shadow Flits Before Me by ladyofthelog. That is all.
