Can you tell us what books she reads comfortably by herself? If she's ready for reading more words on a page, that opens up a lot more. My DS5, who can read at a very high level if he wants to, is just now starting to read independently. His favorite books right now are the DK readers with Star Wars stories. He loves Star Wars, and he likes that there's an index in the back of the books so he can look up whatever he wants to read about. Levels 1 and 2 are great for beginning independent readers; they run 32 pages with lots of pictures and about 3 short sentences per page in level 1, and 4-5 longer sentences in level 2. Level 3 has a couple paragraphs per page and fewer pictures. They have many themes in the DK readers, so there's a good chance your DD will find something she likes. DS liked books about scooby doo for awhile, and there seems to be no shortage of books related to kids shows (for better or worse), and they're all beginning readers.
I second a lot of the other recommendations too. Dr. Seuss is great for beginners, because they're silly and easy to read. Frog and Toad was DS's favorite when he first learned to read.
I'll go track down the threads that discuss the books that are a little more advanced...
