In the process of going back through this series, I've hugely expanded it. The short novella length stories are now full blown novels, but the fourth book, which originally spanned 4 years, has now become 7 novels all on its own. Book 4 is back up on BookApy.com, and book 5 will be joining it soon as well.
You should soon see AWACS disappear from SOL as I'm going to give Amazon Kindle Unlimited a try. I've edited that book again as well, tightening it up nicely.
John the Genius books 4-10 should be rolling out on bookapy for the next few months. My back has been killing me, so I've just been sitting in the only comfortable chair in the house with the laptop on my lap, writing away. 2-4k words a day for a couple months. Once I get to where I'm happy with the rewrites so far, I promise to switch back to Open Hand, Sam's adventure book 2 and get it finished. It should be a fun one.
