Advocate's Choice - The Sentinel Saga, #4

The world has become obsessed with advocacy. Some of it is helpful and necessary. A lot of it is unnecessary and harmful.  The Sentinel notices several trends in this sector that go against the truth, and feels compelled to act. This leads him into a tangled web of deception. Three people in particular - with scandalous and carefully buried pasts - seem to be behind most of it. Can the Sentinel figure out where the twisted path leads before it ends in tragedy?
