From Pan Military Classics, The Korean War by Max Hastings is the best narrative history of the conflict.
On 25 June 1950 the invasion of South Korea by the Communist North launched one of the bloodiest conflicts of the last century. The seemingly limitless power of the Chinese-backed North was thrown against the ferocious firepower of the UN-backed South in a war that can be seen today as the stark prelude to Vietnam.
Max Hastings drew on first-hand accounts of those who fought on both sides to produce this vivid and incisive reassessment of the Korean War, bringing the military and human dimensions into sharp focus. Critically acclaimed on publication, The Korean War remains the best narrative history of this conflict.
