Ten Going on Thirteen (http://dodger-winslow.livejournal.com/38463.html) by dodger_winslow
Summary: For a ten year old, Dean really had the pain-in-the-ass part of being mature for his age down pat.

Red (http://big-pink.livejournal.com/16952.html) by big_pink
Summary: Something evil is killing treeplanters in the forests of the Pacific Northwest, possibly the same predator that Dean narrowly escaped years before. How Grimm will things get before the brothers figure it out? ~79,000 PG-13
**Very absorbing and creepy but you have to be on your toes with the changes back and forth from 3 time frames. An especially satisfying ending.
