RED ANCHORAGE

The Taiwan Strait is about to erupt.

Commander Stellan Rask and the crew of USS Boise are deep behind enemy lines when China launches its long-awaited invasion of Taiwan.

Rask has the enemy fleet in his sights. His torpedoes are ready.

But his communications are gone.

No orders. No authorization. No way to know if Washington wants him to act.

As thousands of troops race toward the shore, one submarine captain faces a decision that could change the course of a war.
