I don't see how POV is irrelevant. Maybe it is different for e-pubs. I only read M/M e-pubbed romances, and yes, a lot of them are 1st person. But go as far as traditional publishing, they still want 3rd person, and POV from the hero and heroine. Go into any bookstore, go to the romance section, and pick a book at random. It would be very hard to find a 1st person romance. Not saying they aren't out there. They might be. But I own hundreds, and have read hundreds more. The only 1st person romance I have read is M/M and epubbed books.
So I stand by what I said
That's quite the challenge you've set forth. Since there aren't any bookstores in my little corner of the rural south, i just went to amazon, and their top ten list:
Amazon's top ten paid in Romance:
1. Entwined with you, Sylvia Day 1st person
2. Honeymoon for one, Beth Orsoff 1st person
3. Beauty from Surrender, Georgia Cates, 1st Person
4. Conquer your love, JC Reed, 1st Person (prologue was in 3rd however)
5. Crazy little thing, Tracy Brogan, 1st person
6. My Side, Tara Brown, 1st person
7. Breath of Scandal, Sandra Brown, 3rd person
8. Beauty from Pain, Georgia Cates, 1st Person
9. One pink line, Dina Silver, 1st Person
10. Whiskey Beach, Nora Roberts, 3rd Person
