Our son continued writing after he published The Knight of Asper. He came up with a second book in the series: Battle with Herobrine. The series title is “The Adventures of Stickgamer135” and it is an unofficial Minecraft novel series for children age 9 and older. You can purchase it on Amazon in either paperback or Kindle format.
So many things have happened in the last two months, I have not had a chance to even blog about his second book. For your information, my children do not play Minecraft with other players, and we limit their time on the computer drastically.
