Order of Firefly comics?

[Melissa in NY]

Can someone tell me the order of the Firefly comics? I found Serenity:Those Left Behind at my bookstore today but didn't know if I should buy it if it's way out of order.
Thanks!

BETTER DAYS comes after the show, then THOSE LEFT BEHIND which comes before the movie.

Those Left Behind was intended to be the bridge between the show and the movie.

Better Days is like a lost episode of the show.
