All-New Firefly #3 — David M. Booher

Following the events at the monastery, Jayne is held hostage by the mysterious and dangerous criminal known only as the Tax Collector. Mal and Kaylee try to negotiate a trade… and it goes about as well as expected from the crew of the Serenity. But they have a plan! And with a little (or a lot) of luck, they might just be able to rescue Jayne and deliver the medical supplies stolen by the Tax Collector's gang.
