Daggermouth (The Heart, Book 1) - H.M. Wolfe

Set in a corrupt surveillance state ruled by the masked elite, this true enemies-to-lovers dystopian romance that’s Conform meets V For Vendetta follows a mercenary who botches the assassination of the president’s son and ends up forced to marry him. The first thing you’ll learn in New Found Haven is that mercy doesn’t exist. The second thing is that, from the highest glass atrium in the Heart to the windowless slums of the Boundary, the Veyra are always watching.
