From our country's most important war historian, a gripping account of the turbulent relationship between Canada and the US during the Second World War. The two nations entered the war amidst rivalry and mutual suspicion, but learned to fight together before emerging triumphant and bound by an alliance that has lasted to this day.

When the Second World War broke out in 1939, it set in motion a deadly struggle between the Axis powers and the Allies, but also fraught negotiations between and among the Allies. On questions of diplomacy, economic policy, industrial might, military capabilities, and even national sovereignty, thousands of lives and the fate of the free world depended on back-room deals and desperate trade-offs between soldiers, diplomats, and leaders.

In North America, Canada and the US strained to forge a new military alliance to guard their coasts and fend off German U-boats and the menace of a Japanese invasion. Wartime economies were entwined to produce a staggering contribution of weapons to keep Britain and other allies in the war. The defense of North America against enemy threats was essential before the US and Canada could send armies, navies, and air forces overseas.

In his trademark style, Tim Cook employs eyewitness accounts to vividly lay bare the brutality of combat and the courage of North Americans under fire. Behind the fighting fronts, the charged and often secret communications between national leaders Churchill, Roosevelt, and King reveals how their personalities shaped the outcome of history’s most destructive war, the fate of the British Empire, and the North American alliance that lives on to this day.

The Good Allies is a masterful account of how Canadians and Americans made the transition from wary rivals to steadfast allies, and how Canada thrived in the shadow of the military and global superpower. In exploring this complex and crucial dimension of the Second World War and its legacy, Cook recounts two nations’ story of cooperation, of sacrifice, and of bleeding together to save the world from the fascist threat.
