Angel's Curse - Angel Series, #2

What lengths would you go to for revenge?Helena is furious beyond belief. She can't forgive the angels for what they did to her, and Danizriel - one of their own kind - who sought only to help her. Now she's out for revenge. A coordinated blitz takes place on the solstice and thousands of vampires lay waste to the angelic host, in an attack orchestrated by Helena. In exchange for her help she receives three weapons from the time of the fall - powerful enough to destroy archangels.
With three archangels down and one to go, Helena gambles with her soul to pull off the kind of bluff that even Satan might fall for. If she loses, the devil takes it all.
