I like my pen-name Billy Elm and it has several advantages, not least of which is that it is unusual. If you google Billy Elm, I will be up there on the first page. Unlike Helen Williams.

I had to register with Smashwords as Helen Williams, as a result of which Delroy and the Marog Princess has to be by Helen Williams, both on the first page and on the cover. I have made this change at Smashwords, so hope I will now be eligible for their premium list.
It is available at Smashwords for $5.99 and for the month of July is 25% off. When that offer closes, I will be putting it on Amazon. You can still download to your kindle direct from Smashwords. You can also have a sample read to see if you like it or if you think your 12-15 year-old would like it. The link to it is
