Angel Breeds: Seven Tears Of War (book 1)

Azelia Sage never felt like she belonged. Constantly moving and still mourning the inability to contact her closest older sister, Samandria, Azelia wants to be finished with living in such a hard life. Her parents treat her unfairly ever since the incident, and to make matters worse, she begins to have visions of the chaotic future involving a bloody war between angels and demons. Unable to understand these visions, let alone make them stop, Azelia does the unthinkable and contacts her sister, who is the only one to know what is wrong with Azelia. After coming to the truth of her destiny, Azelia is to hunt down the other six angels and prevent the gates of Hell from opening.
But someone on the team is about to sabotage all she is working towards, and is dying to see her fail. Who is this person, and will Azelia succeed?
