OK Sierra: A Drama in Three Acts

Sierra is Davin's AIde - an artificial intelligence implanted directly at the base of his brain. In tandem, the two make a powerful team, greatly expanding many of his natural abilities. But Sierra is no typical piece of software. She thinks. She feels. She internalizes Davin's struggles as her own. Their dual existence is utterly dependent upon each other in ways that Davin never quite accounted for.
