Vampire Sins by J.R. Thorn

My fourth is a freaking vampire?
Xavier is cocky, overzealous, and way too hot for his own good. He’s just what I need to stop my nightmares from coming to fruition, except he’s telling me that I’m not supposed to stop the future from happening. I’m supposed to fulfill a dark prophecy. One where I’m the Queen of Hell, turned into a vampire, and I save hell itself from being destroyed.
Hell getting destroyed sounds like a good idea to me, so I’ll have to talk some sense into Xavier, but first I need to get my men all in one place. They’re stuck all over the world and, well, let’s face it, the world’s most certainly gone to shit.
Jet, my dragon shifter, has survived the last loyalists to his brother, but they won’t accept his rule unless he obtains the Dragon’s Eye. He better not die trying to retrieve it… or trying to get back to me.
Nate, my beloved human, is trapped Hell knows where and with my grandmother of all people. He’s full of surprises though, and he might just be the weakest link in my bond that’ll save the day.
When all seven sins reunite, I’ll have power over hell itself. It’s up to me what happens next.
