Rockchick, the best book I've ever read about LoA with love/attraction/sex is
Finding Each Other by Don & Mary Kelly. One of the authors of this little known gem is the author of "Path of the Pearl". The two are husband and wife, and talk about theirs' and others' experience with LoA and love. Their system is very effective. They have led workshops for years that have high rates of success, and the book is the course material.
This is the only book I'll even read on the subject. It is a course/workshop, meaning that you read the book cover to cover and do the exercises one by one. You don't skip steps.
It talks about the inner work you have to do before you even START intentioning love into your life. And they say that the inner work (the book gives lots of processes similar to Abraham-Hicks' processes) can take UP TO A YEAR OR MORE! The book has some very powerful and effective techniques for dealing with your own feelings of unworthiness, loneliness and emptiness and helps a person let go of the neuroses and attachments that keep them from attracting others or having good relationships.
The second half of the book gives LoA techniques for attracting others, but trust me, you really don't want to do the second half without doing the first half... BECAUSE the techniques work.
I really, really, really wish this book would come back into print. I buy it every time I find myself single, and when I'm in a relationship, I give the book to someone who could make use of it and tell them "pass it forward - when you find someone, give the book to another lonely person".
