Yeah, unfortunately/fortunately the sales are tricky to take absolutes from, imo, so I'll try to condense a rambling, ranty post into bullet points;
That
bloody infidelity comment by JDW, *shakes fist in air* WHAT? WHO? WHY? would that be of any benefit to an ongoing books sales, about newlyweds. There was a noticeable drop in sales of about 3000 to 4000, after that comment.
Nothing from JDW or marvel marketing in regards to the couple or the book, KT has been left on her own to generate hype (Monday teasers). They even had a X-Monday session about X-Romances, with barely anything about the couple who Marvel were selling a book about!
The art hasn't been great, not awful at all, but for example, a lot of the emotive beats got dulled by the lack of expressions. It got bloody irritating at times for me.
