The Thorn Queen by Sasha Peyton Smith

Wed to one brother.
In love with the other.

Bridgerton, The Selection, and The Cruel Prince collide in this Victorian-inspired romantasy; the sequel to the instant New York Times bestseller The Rose Bargain.

Having won the hand of the faerie King Bram, Ivy is now Queen of England.
But with his ascension to the throne, Bram unleashed the fae into the human world. After hundreds of years of being kept from their favorite playthings, the Others are looking to make up for lost time—and they do, with wicked revelry that sweeps through the country.
To survive, Ivy acts the sweet, devoted wife. Behind the smile, she plots to banish her husband, save her sister Lydia, and reunite with the love of her life, Emmett.

Yet Emmet and Lydia are trapped in the Otherworld, where fae games are deadlier than ever—and a queen must play most viciously of all. Or see herself dethroned.
