Looking for a book in Thai

[DaQue]

I’m looking for a free, not pirated, book in Thai that I can use to practice reading Thai. I have a book to learn to read, this would just Be used to practice reading , writing , and working out the word divisions. Also if anyone knows of a list of common Thai words that only the tones are different I could use it to work on those. Many thanks if anyone can help point me to sources.
