Drawing on a wealth of his own research and the work of other Lincoln scholars, Shenk reveals how the sixteenth president harnessed his depression to fuel his astonishing success. Lincoln found the solace and tactics he needed to deal with the nation's worst crisis in the coping strategies he developed over a lifetime of persevering through depressive episodes and personal tragedies. With empathy and authority gained from his own experience with depression, Shenk crafts a nuanced, revelatory account of Lincoln and his legacy, and in the process unveils a wholly new perspective on how our greatest president guided America through its greatest turmoil.
