Unfortunately I couldn’t talk the publisher into doing a hardcover edition. (It would be too expensive for what the sales would be) So the 5 collected editions are the best option.
Most of the backups (aside from a few that are set in the Prophet universe) were only in the issues. – Anyway I hope you like the stuff, it was a blast to work on.
