"'The Parallel Worlds' Series" by LouisaB

When I started this blog, I decided to only recommend one fic per author, and that was it. After just a couple of months, I'm already bending the rules, though in my defense, it's for an interconnected series.

I left out one story there - "Catch a Quaffle," technically second in the series, though it has nothing to do with inter-dimensional Marauders as it does Remus/Sirius fluff. And I just don't care about that.

After accidentally opening a portal and finding a parallel universe, the marauders (and Lily!) get into all sorts of adventures and wacky hi-jinks. These fics are actually really well-written, enjoyable, and pretty damn brilliant. The different marauders running around at all times is sure to make you smile. I doubt these fics would be half as popular as they are if it weren't for the RLSB aspect, but I actually feel like that's the weakest part to the whole series.

"The Spy Game" by ttfn.tahtahfornow

This is a really lovely AU fanfic; it's subtle Remus/Sirius, but there's so much more to it than that. It's basically written as if the Marauders were muggles and neighbors and went to the same school.

The plot to this fic isn't exactly amazing, but ttfn's writing style is really lovely. It's more a collection of viginettes than a fleshed out novel, but the pacing is done well - so well, in fact, that her lack of description seems to be almost the perfect way to write. She never hits you over the head with anything, and when the threads come together, you just have a nice a-ha moment in your head.

If I had any complaints it would be that it's a bit angsty, but not even I, who HATES angst (I really do), was turned off by this fic - the author just hands it all so delicately that scenarios that would be eye-rolling in any other fic just make you desperate for more in this one.
