I haven’t read a book in years and I’m struggling

I've realized I haven't read a book outside of manrory school reading but Ive barely a life outside of my work at the cat shelter so I decided to take up reading but the words are difficult for my brain to read and I was struggling and feeling bad but I've learned that a lot of adults can't read above an 8th grade level and I probably shouldn't be starting with a big adult book but if I want to relearn I should read something easier to comrehemd

What books would recommend for someone wanting a good story but can't read a hard adult novel and needs some books to ease me into reading at all but still good and not bad books? I think I like fantasy and adventure and magic!
