While waiting for the mini Firefly reunion with Summer and Nathan Fillion on set of Castle, take a look at a book of behind-the-scenes photos taken (mostly) by Nathan Fillion whilst on the set of Firefly! This small but sweet photo book, filled with personal photos featuring the Firefly cast and crew, was a stand alone perk for crowd funding Alan Tudyk and Nathan's web series Con Man.

Check out below a few scans of these beautiful and tinged with nostalgia shots from the camera of Nathan Fillion.
