Crossover recs

Crossovers have a bad reputation. You think "crossover" and you think "badly written drivel that has nothing to do with either series" and no one wants to read that crap. I am here to tell you that crossovers need love, too. Crossovers can be just as well-written as any epic, any AU, any other genre at all. A good crossover doesn't require you to be intimate with both (or all) of the series used. A good crossover is just plain good.
