M2, the official name for the second book in the Mermaid Adventures stories now has a title, "The Mermaid's Apprentice," a cover and has been proofed in book form and is now available. (Whew!) On with M3!
Currently it is available on Amazon.com as the paperback and e-book, as well as the two Google Play and Books e-book versions, plus a host of other locations.
