If you're lucky enough to get a few days off this holiday season, consider adding one more tally to your "2016 books read" list and impressing your boss when you return to the office in January. Below are six books that we hope will educate and inspire. In the spirit of shoestring nonprofit budgets, the price listed is the cheapest used book price on Amazon.

• The New Jim Crow: Mass Incarceration in the Age of Colorblindness by Michelle Alexander ($7.73) -- A powerful book for anyone working with youth of color or seeking to expand their anti-racist vocabulary.
• Mountains Beyond Mountains: The Quest of Dr. Paul Farmer, the Man Who Would Cure the World by Tracy Kidder ($0.01) -- Interested in public health, Haiti, or international development? This one's for you.
• The Cathedral Within: Transforming Your Life by Giving Something Back by Bill Shore ($0.01) -- A quick, inspirational read with vignettes about nonprofit leaders who built programs and goals to last the centuries, like cathedrals.
• Lean In: Women, Work, and the Will to Lead by Sheryl Sandberg ($0.01) -- Still haven't read this 2013 call to arms for women in the workplace? Get it. Particularly important for men who identify as feminists.
