"Angels: A book for self realization through angels and your personal guides-" is a quick-read.
"Synchronicity: Coincidence, Happening at the Same Time, Simultaneous" is a quick-read. Your free will is important, but it can also block help from your angels and guides. Unless you are totally aware of what is in your best interest, you could take too many wrong turns and end up in the wrong place; something that would not happen if you were in touch with your angels and guides-more importantly, if your angels and guides can get in touch with you.
