April 16th excerpt: 

Jacob looked up in awe. Dean’s boot alone would be impossible to see over. Hell, just the rubber sole was almost as high up as Jacob’s current stature. The towering, jean-clad leg above the boot stretched high overhead. Jacob could scarcely imagine what it’d look like to see Dean standing from a view near his feet. The thought almost gave him vertigo and Jacob had to stare at his knees for a few seconds to let the moment pass.

Unbothered by the size of the boots and the limb before him, Sam came right up to the heel and started the easy climb up to Dean’s knee. He scrambled up the towering leg, fingers easily finding purchase in the thick threads. Jacob was amazed by how quickly Sam climbed up that tower of denim. It was practically second nature to the guy after spending a year around humans. Jacob could even recall a time or two when Sam had climbed up his leg like that.
