Angela Duckworth's Grit: The Power of Passion and Perseverance - I thoroughly enjoyed Duckworth's book. Though I'd listened to her TED Talk and heard her interviewed several times on the Freakonomics podcast, this expansion of her theories and discoveries is thought-provoking.
Michelle Obama's Becoming - Michelle Obama's memoir is so perfect. Her account of her childhood, coming of age, marriage to Barack, and slide into her new identity as FLOTUS is moving and honest and vulnerable. She doesn't hide her struggles or her flaws, and I so appreciated her perspectives on what she learned and how she grew as a person. What a memoir.
