Story: Aliens in the Backyard
Author: Raven Aorla
Rating: All Ages
Word Count: 4038
Author's Summary: Calvin is really, really good at attracting attention from aliens. Usually Hobbes merely bears this, but now he has a reason to call for help, and a certain blue police box makes an appearance in a forested suburb in Ohio. Crossover with, you guessed it, "Calvin & Hobbes". Spoilers for "Last of the Time Lords".
Characters/Pairings: Tenth Doctor, Martha Jones, Susan, Calvin, Hobbes, Susie Derkins
Recced because: Time Lord!Calvin isn’t a new idea. And if you just read the first chapter of this fic (there are four total), what you get is a fun, lighthearted Time Lord!Calvin fic. Keep going, though, and the fun, joyous improbabilities of Calvin’s world start to peel back, one by one. This goes from being an easy read to a hard one so quietly that you don’t even realize it until you’re halfway through the fourth chapter crying your eyes out, and it will haunt you (and your Calvin and Hobbes rereads) long after it’s done.
