How do you book apointment?

Seeing as this is under the category "Book of Mormon" I will assume you mean an appointment to learn about it?

You can call and set one up immediately: "1-888-537-6600"

you can chat with an online representative: "mormon.org/chat"

you can fill out your info and have the missionaries contact you: "mormon.org/missionaries"

Or you can just attend a Sunday service. To find a place and time near you, go to: "mormon.org/worship"
