Meet Sam Hitchcock Wilson. He's your average self dubbed 'super-nerd'. Except for the fact that his life has successfully bored him to death.
So how do you get from attempted suicide to waking up surrounded by colorful ponies of various autonomic features? Sometimes, it's better not to ask and just hope Cthulhu doesn't have his slimy tentacles in this somehow. Of course, a human can never just innocently stumble into Equestria. There always has to be some dark reason behind it. Stick around, you might just find out what that reason is for this poor human. Or Discord could pop up and give you the middle finger. Whichever works for you.
((I know there are already a million 'human in Equestria' stories, but I hope you'll give this one a chance. Who knows? You might be glad you did.))
[Haven't sprung for the 'Dark' tag yet, but I might, so you've been warned]
