Rite of Blood and Secrets by Laura Greenwood

A deal with a vampire changes Beatrice’s life forever.

Beatrice always thought she’d have a simple life, and definitely not one run by court intrigue and factions battling for power. But when her twin brother reveals a family secret, all of that changes.
The decadent world they find themselves glitters from the outside, but beneath the surface lies something sinister, and Beatrice is determined to do everything she can to survive and not draw the attention of the wrong person.
With no idea who to trust, Beatrice has to keep her wits about her, even if they’re almost stolen when she encounters a handsome stranger.
There’s only one thing for certain, Beatrice’s life is never going to be the same again.
