Queen of Darkness by Elise Knight

Surviving my own nightmares is one thing, but now I’ve evoked the wrath of the Dark Queen, and unlike her sons, she will not stop until I’m dead
The war between the real world and the dream world is hotting up and the veil separating the two is close to dropping and annihilating them both. The same can be said about my relationship with Dream, except it’s not just an army of nightwalkers that threaten us. Because the truth is, humans cannot survive in the Realm of Night and Dream cannot leave it. Dream’s inner demons are worse than the actual demons that threaten us and no matter how searing hot our relationship is, I have to make the choice of what to save. Dream or the world he lives in.
