Set during the depths of the Great Decline (2314 C.E.), The Cascadian Mission is the final book of the Whitehorse Chronicles. North American society has fragmented as a result of climate change and resource depletion. The Valley government (formerly the Yukon) enlists Amy Brown, Cap Ironshank and Joe Otter to accompany Leon James, the chief envoy, to San Francisco on a mission to discuss boundary and trade issues with the government of Cascadia (formerly the west coast of United States and part of Canada).
The mission is shipwrecked near Prince Rupert and Amy is separated from the main party. Her struggle to re-join her colleagues involves some fascinating encounters with a colourful cast of characters. Meanwhile, on the way to San Francisco, a mysterious woman representing a revolutionary faction within Cascadia approaches Cap with an important proposal. This meeting and subsequent Confederate-Cascadian intrigue put the delegation in danger. Cap must find Amy and then carry information that is crucial to Valley survival back to Whitehorse.
