The Crisis Artifact is the first book in the Crisis Trilogy. The books in this trilogy are more like novellas in length, but a lot of story's packed into them.
Caesar Guevara was an archeologist. Then he was seriously injured and his daughter killed in an accident while on a dig in the jungles of Peru. Now he's a derelict living in east LA, but that's about to change. Caesar is about to find what he's spent years looking for, or it's about to find him. Not the best flow or dialog, but the story is good and keeps you turning pages. Recommended.
