Question and Answer

Q: What grade level is WA Interactive?

A: For upper elementary and middle school.
Q: Is there a fourth Three Vests book coming out?

A: Our most frequently asked question. Unfortunately, there are no plans in the works for a fourth book in the 3V series. If that changes, we'll announce it here.
Q: Do the other books connect to the Three Vests series?

A: Yes in many ways. You don't have to read one book to enjoy the other. However, it will make for a more enriching experience if you read in this order: Three Vests I, II, III - followed by NPSP - and then Chase The Silver Ghost
