These books are so nice that anyone who reads them is sure to become Krishna Conscious. You can show them Krsna books and ask them to read any part and if they like what they have read they should purchase, and if not you will walk away. Who could resist? Krsna book is so nice that everyone will like it, either as a story book or history or philosophy or whatever, they are sure to be attracted. Simply it depends on your presentation. So do it nicely and Krsna will help you.
