A blog tour is a great tool for authors to promote their books. The author will arrange for bloggers to read and review the book on a specific day. The author will then direct traffic to the bloggers site. I've participated in blog tours in the past and love doing them. Here is a list a blog tours on my schedule right now...
June 11 - Heaven Scent by Rebecca Cornish Talley
June - Don't You Marry the Mormon Boys by Janet Kay Jensen
July - All's Fair by Julie Coulter Bellon
August - Surprise Packages by Lael Littke, Carroll Morris, Nancy Anderson
August - Farworld: Water Keep by J. Scott Savage
