You can check out the Absolute Beginner Book Club. It lists past book clubs, and there is one happening right now and not so far from now as well. It has the advantage, that you get a vocab sheet as well, which can help with reading a ton.
Also check out Natively, it ranks books based on difficulty.
I’ve tried Doraemon, Teasing Master Takagi-san, and Pokemon special and so far I’ve stuck with Pokemon the most.

As a follow-up, and I hope this isn’t against the rules here, but could anyone point me in the direction of a good free manga-reader site/app where I would be able to read these manga in Japanese?
