I've been into MMM for all my adult life and my finances are pretty much on autopilot these days. However, my mom has recently come into her inheritance and I'm helping her figure out how to use it to retire. I understand how to do so and am helping her out but she is definitely more worried about the math and trusting that she really can afford to stop working. She's always been very good at the spending side of financial planning, never really earned much money, but also never spending much or getting into debt either. However, she's never had enough money to bother learning about investing and that part of financial planning so that feels scary / overwhelming for her. But she's also not the kind to just hire an advisor. I'd like to get her a book to help her understand retirement planning that does focus more on the investing / money management part of it than the spending part.
Anyway, my question is does anyone have good book recommendations for someone like her?
