Serenity: Better Days, from Joss Whedon and Brett Matthews, follows everyone's favorite space cowboys in an action-packed adventure where the crew takes on a heist that promises a big payoff. But when someone is taken captive, the gang must put aside their enduring differences and work together, at the risk of losing their cash prize.

Joss Whedon's Emmy award-winning musical tragicomedy tells the story of Billy, aka Dr Horrible, a budding supervillain who wants to beat superhero Captain Hammer and take over the world... and pluck up the courage to speak to his laundromat crush Penny. With exclusive new material from Joss and the production team, new photos, sheet music and more, this official book is a must for fans.

Before the smash hit movie Serenity came Firefly, the cult TV series, which started it all and became a DVD phenomenon, selling almost half a million copies. Set 500 years in the future, Firefly centres around Mal Reynolds, captain of the ship-for-hire Serenity and its eclectic crew of galactic misfits. When he takes on two passengers, a young doctor and his mysterious, telepathic sister, he gets much more than he bargained for... This official companion is just what the show's fervent fans, the 'Browncoats', have been waiting for, with unseen photos, scripts, behind the scenes secrets, and exclusive input from the cast and crew, including of course creator Joss Whedon.
