I bought 4 series romances at the supermarket today. 2 from the "Intrigue" imprint and 2 from the "Historical" imprint.
I totally ignored the author's name and went only by the imprint title and the blurb on the back of the books. Actually. It's amazing how many imprints there are nowadays. I could see "Super Historical", "Instant Family", "Baby on the Way"; all in addition to the usual "Medical", "Blaze", etc.
Unfortunately. At the check-out I was somewhat surprised by the cost of each. Nearly as much as a proper romance novel.
