From Valhalla (en Inglés) - N. von Wolf

Vampires weren't just real-they were kings. The Ragnulfs, once Viking warlords, now vampire nobility, rule with blood and conquest. Sent to their fortress as an Oscurelle, Elise von Albrecht knows her role: to serve. But Erik, the warlord, and Magnus, his shadowed, sinful brother, want more than her obedience. They want her.

Bound to one, tempted by the other, Elise is caught in a sensual battle between dominance and desire. But as Ancients are murdered and war looms, she must decide-be their pawn and let them tear her apart, or become their queen and join their wars.

In the arms of Viking monsters, love is war.
