Firefly: Still Flying -- A Celebration of Joss Whedon's Acclaimed TV Series
A shiny collection of pictures, stories from the set (like Fillion's infamous stuffed monkey prank), interview tidbits, convention appearances, and four brand new stories from Jane Espenson, Jose Molina, Brett Matthews, and a two page illustrated story by Ben Edlund. The book is put together beautifully with glossy pages and a loving hand, but it made me sad about Firefly all over again, gorramit.
(Just goes to show that when you really love something, you never get over losing it.)
