PFIN 4 (with CourseMate, 1 term (6 months) Printed Access Card) (New, Engaging Titles from 4LTR Press) 4th edition by Gitman, Lawrence J., Joehnk, Michael D., Billingsley, Randal (2015) Paperback
I think it's a great textbook for personal finance. There's many things a person can learn and apply to their financial life. Especially for teenagers who want to start saving money and want to know how to spend money wisely, it's defiantly a start. It explains many concepts and calculations. It's also great for a personal finance class.
