Ok, so I know I read this book within the last few years. It takes place in the 2010s I think. So I know there a vampire queen who is in danger due to demons being let through onto earth and also someone is kidnapping and murdering werewolves. So to build defences and figure out how the wolves are dying the vampire queen marries a werewolf alpha.
Possible spoilers! I know when they mate for the first time the building they are in gets set on fire, since vampires can die to fire, and the alpha left for a few minutes during the day and comes back and goes into the burning building to save the vampire queen. She lives but is really injured. They try to figure out who is trying to kill her while also trying to find out who is letting the demon creatures in. They find out towards the end of the book that the vampire queens consultant or 2nd in command is the one letting demons in and killing the werewolves.
