Books for 7-year-old to help with reading, preferably with pictures but not 'picture books'.

Hi, my daughter is 7 and is starting to get reading but finds it difficult. She often also finds the "learn to read" book tedious. She really likes listening to audiobooks, particularly chapter books and mysteries like "the boxcar children." She also likes fantasy stuff, dragons, nights, wizards, faeries, etc. I'm having trouble finding a book or series that will

a) hold her attention, not be to babyish
b) features enough easy words that we can read it together, me reading most of it and letting her practice a bit throughout.

So, i think the ideal book would be an easy chapter book with pictures. Dory Fantasmagory is an example, but we've already read that together and she's not interested in reading it again with us. We've been doing Dr. Seuss, which she likes and is good, but I'm hoping for something that lasts a little longer, encouraging her to come back to it every night.

Thanks! I'm open to other suggestions for helping her with reading too.

edit: y'all are the best as usual. I have enough books to last her until she's 30. I'll sort through some, try some, and let you know if any work particularly well. for posterity.
