Guardian Angel Publishing publishes books for children ages 0-12. They publish e-books, print books, books on CD, and soon they will have books on DVD, so that children can actually watch the books on their television. The company calls its authors and artists its guardian angels. They have books about subjects ranging from health and hygiene to animals and pets to faith. They also carry chapter books for "tweens." Their books are not just reading material, though; they have morals and values instilled in each story. There are several different titles available, and we were recently able to review four of those.
(Disclosure: I was provided with these free e-books by Guardian Angel Publishing, in association with the TOS Homeschool Crew.)
