I'm reading the most interesting Sentinel story, I've ever read. Very different, but very good so far. I'm recommending even though it's in parts, because Katef has never not finished her stories. She works on one at a time. It's up to Chapter four now, and I see many more chapters to get to the end. I just love it so far and hope you'll check it out if you have time. It's totally AU, slash and there is angst.
