The stories by Espenson, Matthews and Molina are between five and seven pages long. Espenson's story, 'What Holds Us Down', is a suspenseful tale focusing on the characters of Kaylee and Wash (played in the series by Jewel Staite and Alan Tudyk). 'Take the Sky', by Molina, is a touching tribute to Fillion's character, Malcolm Reynolds, with a neat twist. Matthews' 'Crystal' has some touching moments but I found it to be the least interesting by virtue of it being based on a familiar idea (River has premonitions of the deaths of each of the Serenity's crew members). Edlund's contribution, 'Fun with Dick and Jayne', is a bit different from the others. It's not a story as much as a vignette in the form of a two frame comic strip across two full pages. One of the images is somewhat violent and you might want to consider this if you are thinking of buying this book for a child.
Firefly: Still Flying maintains Titan's high standards for film and TV tie-ins. Intended as a celebration of Joss Whedon's creation, it is a fine complement to the show and to Titan's Firefly Companions. If the content is within your sphere of interest, I highly recommended this book.
