Unfortunately, I reorganized my backlog today and the bookcase with the romance novels is doubleshelved, and those are on the back row, so i can't look and give you details (though I'm sure Andrea Pickens has a website) but they're basically, as I understand it, a trilogy of Regency Historicals about female orphans raised to be spies. I've only read one other book by Pickens, which was written under the pseudonym Andrea DaRif, but I liked it.
