Yes, it is. I won't spoil it for you but be sure to try it out. I bought both volumes of the TPB even though I have the singles issues two. I figure that's one way to support the character and who knows? Maybe another mini series or ongoing could come along one day.
After the first 6 issues came out, it was nominated for an Eisner Award for best new series, which IMO indicates that at one time it was considered an ongoing series. Then the pandemic came along and threw everything off. It did end with issue #12 but Cantwell has said in several podcasts that he had the next arc planned.
