I'm going to take a different approach here. Due to the nature of your book and because one of my publisher's authors (Doreen Virtue) and I spoke about book promotion, I am going to suggest allowing spirit to open doors that should be opened. Doreen has sold a ton of books and she refuses to self-promote.

I've had it happen in my own life. I, of course, put myself out there but allow God to do the rest. I do make contacts with shelters, etc to help them and to donate my book but I have never actively gone on a promotion gig. I detest book signings and have even turned some down. My publicist agrees with me that they don't really sell that many books unless friends and family show up. I'm not saying that people don't sell at them, it's just not my thing.

I would also suggest that you try to book speaking engagements on your topic. That way, you meet people and they want to hear more and buy your book.

Okay, that's my two cents.
