Aliette's new book,
Of Dragons, Feasts and Murders, will be out in July.
At the moment you can only pre-order the kindle version, but she says there'll be a print version too.
It's set in the same world of the
Dominion of the Fallen world and centers around Asmodeus and Thuan!
It's got a great cover


Blurb:
From the author of the critically acclaimed Dominion of the Fallen trilogy comes a tale of dragons, and Fallen angels — and also kissing, sarcasm and stabbing.
Lunar New Year should be a time for familial reunions, ancestor worship, and consumption of an unhealthy amount of candied fruit.
But when dragon prince Thuan brings home his brooding and ruthless husband Asmodeus for the New Year, they find not interminable family gatherings, but a corpse outside their quarters. Asmodeus is thrilled by the murder investigation; Thuan, who gets dragged into the political plotting he'd sworn off when he left, is less enthusiastic.
It'll take all of Asmodeus's skill with knives, and all of Thuan's diplomacy, to navigate this one — as well as the troubled waters of their own relationship....
A sparkling standalone book set in a world of dark intrigue.
And what she says

"it combined the tropes of Asian court drama (I was watching Nirvana in Fire at the time) with Gothic comedy of manners, in which an unlikely duo had to cooperate with each other to navigate political intrigue and solve a murder. That duo were a bookish dragon prince and his ruthless Fallen angel husband: they came from my Gothic Paris Dominion of the Fallen series, but the story itself was totally standalone.
I had a blast writing it, and my hope that you will have a blast reading it as well, because this seems to be the perfect time for a fun and fluffy (*) book involving a mismatched couple, dollops of embarrassing moments, and the occasional kiss.
(*)"fluffy" for Bodard values of fluffy. It still involves a murder investigation, and ideas of consent and rulership and change, because, well--
*helpless shrug*"
