Reddit mentions of Sorcery and Cecelia or The Enchanted Chocolate Pot

I don't read much historical fantasy, but I have read some and some more alternate history if you are in to that. I haven't read the one you spoke of in your post, so not sure exactly what balance of history and fantasy (or time period) you are looking for. However, I will list here for you many that I have read:

The Shadow of Albion - Andre Norton and Rosemary Edghill Alternate England

Black Ships - Jo Graham This one is about Troy. some romance

His Majesty's Dragon - Naomi Novik Napoleonic War with dragons.

Daughter of the Forest - Juliet Marillier The author says it isn't historical, but it is based somewhat on history/legend. Ireland as it is being exposed to Christianity. Based on The Hans Christian Anderson fairy tale "The Wild Swans" Definitely a good bit of romance in this one.

The Wild Swans - Peg Kerr Another based on the Anderson Fairy Tale. 2 stories in one. One set in the 1800 about a curse, and the other set in the 1980s about AIDS. Not my favorite, but an interesting parallel.

Bright Sword of Ireland - Juliene Osborne-McKnight This one is more mythic and definitely has "romance". It's about Mebd's daughter. Not my personal favorite, but the ending definitely stuck with me. Also deals with interactions with Christianity

Newton's Cannon - Gregory Keyes Okay, haven't read this one yet, but I've been meaning to get around to it.

Young Adult

Sorcery and Cecilia OR The Enchanted Chocolate Pot - Patricia C. Wrede and Caroline Stevermer

A Matter of Magic - Patricia C. Wrede

A Great and Terrible Beauty - Libba Bray

These above are set in London/England in 1700-1900?. They are all relatively light reading.

The Fetch - Laura Whitcomb This one is set during the Russian Revolution. Teen love.

A Certain Slant of Light - Laura Whitcomb This one is set in the present day, but one of the main characters is a ghost from the late 1800s.

There're also quite a few novels in historical fantasy romance. But most of them are definitely more on the romance side.

The Mistborn Trilogy by Brandon Sanderson is a great fantasy series for YA fans branching into adult Fantasy. In fact, they are re-packaging them in PB for teens because they have such good cross-over appeal

I really liked Sorcery and Cecilia, which is Jane Austen with magic, basically.

Speaking of Jane Austen, For Darkness Shows the Stars is a great YA title that's basically a re-telling of Persuasion done in a sort-of dystopian, far future setting.

If you want a more literary contemporary YA, I would try I'll Give You the Sun. It's probably the best book I've read all year.

I've got more where that came from if you would like more titles!

Sorcery and Cecelia, or the Enchanted Chocolate Pot by Patricia C. Wrede and Caroline Stevermer? Both are established authors, and they wrote this book (and its two sequels) by playing "the letter game" - they never discussed plot in advance, only writing the story via letters in-character.

Sorcery & Cecilia is one of these but with fantasy elements, if you're into that.
