Simon Tam will do anything to save his little sister from the Alliance. It'll cost him everything-- his wealth, career, parents, and a perfect life on the Central Planets. But the love between them, a love more dangerous than madness, will persevere as Simon goes undercover into the Alliance to get her away from those that hurt her at any cost. In addition, it's time for a Christmas Carol, Firefly style! Jayne's selfish behavior receives the unwanted attention of three visiting spirits who reveal the hidden past, present and future of Serenity's most... miserly crew member. Acclaimed writers David M. Booher (Canto) and Jeff Jensen (Green River Killer: A True Detective) as well as artists Andrés Genolet (Runaways), Vincenzo Federici (Red Sonja), Jordi Pérez (Xena: Warrior Princess), and Fabiana Mascolo (The Dark Crystal: Age of Resistance), finally reveal the origin of the greatest sibling bond in a story no Browncoat can afford to miss, as well Firefly's take on Dickens' beloved cautionary tale. Collects Firefly: River Run #1 and Firefly: Holiday Special #1.
