Marketing books

I have two books that are published and I want to market them. My first book, "Mind Full of Scorpions" is a journey through severe mental illness and my second book is "Daily Meditations With Your Cat" which is an inspirational book centered around sages, saints, sinners, hymn writers, poets, and of course cats. I do not have the money to put into a professional marketing package so I'm looking for inexpensive or fee methods to do some kick ass marketing. I need to generate royalties from my books, but more importantly I want people to read them and receive help. Kathy Tapley-Milton
