From HarperTeen

The Gentleman's Guide to Vice and Virtue meets Jane Austen in this witty, winking historical romance with a dash of mystery!

Lady Victoria Aston has everything she could want: an older sister happily wed, the future of her family estate secure, and ample opportunity to while her time away in the fields around her home.

However, Vicky’s comfortable, idyllic life is overturned in the course of one night. Her sister’s husband turns out to be a terrible cad and now Vicky must marry, or find herself and her family destitute. Armed only with the wisdom she has gained from her beloved novels by Jane Austen, she enters society’s season in a flutter of silks, dances, and pretty words.

But Miss Austen has little to say about Vicky’s particular circumstances: whether the gorgeous and roguish Mr. Carmichael is indeed a scoundrel, if her former best friend—the much-grown and very handsome Tom Sherborne—is out for her dowry or for her heart, or even how to fend off the attentions of the foppish Mr. Silby, he of the unfortunate fashion sensibility.

Most unfortunately of all, Vicky’s books are silent on the topic of the mysterious accidents cropping up around her. . . accidents that could prevent her from surviving until her wedding day.

What would you do to save your home?

Victoria Aston's about to learn that sometimes nice girls can't follow the rules...

Frequently asked questions

How do you pronounce your name, and where does it come from?

My parents named me after a Dutch fashion model they saw on TV. Although it's not the original Dutch pronounciation, I go by "JEN-ih-kuh Co-en"

What are some of your writing influences?

I tend to draw inspiration from history, folklore, and the great female novelists of the past, especially Jane Austen, the Brontës, Lucy Maud Montgomery, and Daphne du Maurier.

Who are some of your favorite contemporary authors?

Tasha Alexander, Sarah Addison Allen, Lisa Kleypas, Shannon Hale, Susanna Clarke, and Jessica Day George. In general, I also love great fairy tale retellings, anything with suspense and/or adventure, cute romances, and happy endings!

The main character of "Dangerous Alliance" is essentially a Jane Austen fan before "fandoms" existed. What are your favorite Austen novels?

My personal favorite is "Pride and Prejudice" because I do feel like it's the most fun. I really also love "Northanger Abbey" because it's clever and snarky and Henry Tilney is arguably the most "modern" gentlemen of Austen's "heroes." Mr. Darcy is great and certainly swoon-worthy, but Henry Tilney is the type of guy I think I'd like in real life. "Persuasion" used to be near the top of my list, but after re-reading it recently I had a difficult time relating to Anne Elliot. Really, I love them all. Even "Mansfield Park"--although I do have to skip Mrs. Norris's diatribes when I re-read it. She is seriously the worst.

What are some of your favorite movies?

I have too many to count! But if we're talking comfort movies I watch over and over, I'd have to say: Robin Hood: Prince of Thieves, French Kiss, America's Sweethearts, Pillow Talk, Romancing the Stone, Stowaway, Sense and Sensibility ('96), Gigi, Clueless, Tangled, and Austenland. This doesn't include all my love for films in a number of subcatagories like epics, movie musicals, suspense, and great film essentials, any of which I will be happy to discuss with you on social media!


  • I love exploring new places and historical sites. The farthest north I've ever traveled is Oslo, Norway; the farthest south is Christchurch, New Zealand.

  • I'm a sucker for flowers, gardens, and the color pink.

  • When I was a kid I loved swimming. There's even video footage of me exclaiming over and over that "I'm a fish." I can only hope this footage will never be shown outside the family.

  • In middle school, I begged my mom to drive me to the local art house theater (40 minutes away) to see Kenneth Branagh’s full-length film version of Hamlet. #SoWorthIt

  • I will always choose mustard over ketchup ;)
