I have a six year old who is not diagnosed dyslexic but stealth dyslexia has been tossed around as a possibility so I keep it in back of mind.
We also have found Diary of Wimpy Kid to be the easiest read. He was not tired out by it nor did he make the same number of mistakes when reading out loud.
Timmy Failure is another good option. I see that is on the list provided. I can vouch he did well on that book.
I read you have a Kindle Fire. We downloaded a few different reading apps on our device and also the opendyslexic font which is similar to the font used in Diary of Wimpy Kid. He uses that font when available on a sepia background and I believe (though I might be imagining things) he has less reading fatigue.
