Halo: Uncovering the Truth (Book 3, Arbiter x Female human series.)

Bria had been enjoying life. With little to no combat, and constantly helping people, her and Arbiter have a great life together. That is until Arbiter gets called to an unknown mission without her and literally disappears. In Bria's frantic search, she discovers that the clan that she tried so hard to get away from in the past, is back in action. With memory loss and a hunger for power, can she find Arbiter before its too late?

If you haven't already, please read the first 2 books or you will be very confused. Thanks!
