• Of all my books, The Duke and I was the most difficult to title. I have a personal fondness for Daphne’s Bad Heir Day, but How to Bear and Heir was also a contender for the "Most Fun Titles You Never Used" award.

• Eagle-eyed readers will spot a few of my favorite characters in the pages of The Duke and I. Lady Danbury, whom everyone loved so well in How to Marry a Marquis makes an appearance, as does Robert, the hero from Everything and the Moon (although I don't think he actually says anything.) Also, Riverdale, as in James Sidwell, the Marquis of How to Marry a Marquis, is mentioned in Chapter One.

• While I was writing this book, someone very close to me was diagnosed with Multiple Sclerosis, and so I've decided to donate a portion of my royalties to the National Multiple Sclerosis Society. Scientists are getting closer to a cure every day, and in my book, that will be the greatest happy ending of all.

• The Duke and I is first in the Bridgerton series. #2 is The Viscount Who Loved Me, #3 is An Offer from a Gentleman, #4 is Romancing Mr. Bridgerton, and #5 is To Sir Phillip, With Love.

• Lady Whistledown, the gossip columnist featured in, An Offer from a Gentleman "narrates" her own anthology in The Further Observations of Lady Whistledown. This book is not, however, a part of the Bridgerton series.
