Cryptogram updates

Hello everyone
You will not need to have my books to solve the cryptograms that I am leaving at each blog stop on my tour. I created these to challenge you. I am not going to provide a cipher key to help you, the challenge of this is for you to figure the cryptograms out for yourselves. I actually solve cryptograms every night before I go to bed without any help of a cipher key. But here is some information to help you if you are not familiar with cryptograms. What I am using is called a substitution cipher, what this means is that I am substituting one letter of the alphabet for another. This is the same kind of cipher I am using in my books.
No letter ever stands for itself, for example, a C will not stand for a C. The most common three-letter words include; the, and, but, for & are. Common two letter words are; it, is, of & in. The order of frequency of the most used letters in the English language is; E, T, A, O, I, N, S, H, R, D, L, U. Think of your blends and digraphs and that will help you. I am offering a free book to anyone who can solve all of my cryptograms and e-mails the answers to me at the end of my tour. I hope this helps everyone.

Just in case you cannot find the cryptograms that I have left behind so far, here they are.
