This biography has two gimmicks. First it is told in the second person addressing Lincoln. Second it sets up each section leading to a "decision" that Lincoln made giving four alternatives. Neither of those is a complete success, and both annoy. Real, fundamental decisions rarely come with four equally clear tracks you can switch to but are more the result of the surveying that was done long before any track was laid.
But there were the frequent quotes from Lincoln and I did learn a number of things about Lincoln and the Civil War I should have attended to before this. ( )
