I just Just completed a novel titled, "Ezekiel's Eyes", A faith based story of one mans journey into the realm of the supernatural, to wage spiritual warfare against evil, with the souls of his friends, himself and mankind's hanging in the balance. Due to be released by mid march.

What is the best/most efficient way to get a book out to the public?
