Thank you! *runs off to read*

Yay for podfic!! :-)

Here are a few of my favorites: http://twasadark.livejournal.com/tag/podfic+rec

Thank you, and I love your icon!

1/minkmix writes some amazing casfics in which the monsters (etc.) are generally pretty creepy. You could start with "Some people paint"
http://minkmix.livejournal.com/177144.html
and her SPN multi-chapter tag
http://minkmix.livejournal.com/?tag=spn+multi-chapter

2/ If you're looking for shapeshifters and excellent plot, Beasts and Outlaws (http://calamitycrow.livejournal.com/8282.html) is the way to go. Plotty, long, and amazing.
There are more, and I'll try to come back and rec 'em as I remember them, but those two are really cool.

6/ Fave podfic is Lingering in the Golden Gleam (http://audiofic.jinjurly.com/lingering-in-golden-gleam-audiobook) by causeways (J2, AU-but-not-really future!fic). I also really enjoy anything recorded from chash [generally AU J2]and the tag for those is right here

I'm not finished listening to it, but fanfic_read_by recently released Old Rebel Yeller (http://audiofic.jinjurly.com/old-rebel-yeller-audiobook) [SPN, Gen], and I've liked it so far.

:D Awesome, Thank you!

If you don't mind self recs I've got a couple of long casefics. Hozho is about a skinwalker, a type of shapeshifter, but I tried to stay close to the Navajo legends so the character is different from the show's shapeshifter.

The Highwayman

Self recs are fine, these both sound interesting. Thank you :D

There is an extremely good but very long work in progress by Dodger Winslow about shapeshifter and John Winchester. Called 'Skin Deep'. Can be found at the following address (and at Papa Winchester) http://dodger-winslow.livejournal.com/108187.html#cutid1

Sounds great, Thanks!

Best shapeshifter verse EVER, very dark and chilling
