Quite a hefty tome, and written by Judith Lieu (Cambridge). Logos has several of her volumes:

She tends to concentrate in the 2nd century, and the church's development.
This book is recent (2015) .... I don't know how I missed it. Maybe the price came down.
Marcion is sort of an oddity. First, he was a PK (technically BK) ... he began on the inside. Second, he didn't propose to have spectacular authority (the Spirit, a bishop, prophesy). Basically, his arguments were his 'success' and indeed, he became a major player. So, much so, that his writings are preserved by his critics ... and surprisingly quite a few.
But the other curiousity, is that the early 'fathers' made their apologetic arguments using the OT ... not Jesus (a little Paul thrown in). And this, after Jerusalem/Israel had been destroyed by the most hated of enemies.
Marcion reversed course, denying the OT/YHWH and re-building on Paul, complete with an authorized canon. And a sizable portion of the church agreed.
So. An excellent (and affordable) book on this whole 2nd century shift. Recommended.
