I found this to be a great guide for many different options regarding impact investing. It would be good to have a starting knowledge of investments (or as suggested by the authors to read their first book), and then this is an easily understood guide. It covers what impact investing is, common dilemmas, following your inner values, investing basics, mainstream options and beyond, strategies for impact investing, and non-investing ways to be a changemaker.
There's a glossary at the end, but the book was full of explanations and ideas, and while it gives a lot to think about, I found it helpful as it laid out steps in order. I recommend this for individuals interested in doing something more with money than just investing in the stock market.
