It's great that your daughter enjoyed the Junie B. Jones series. Here are some others that she would probably enjoy. Judy Blume's books, the Ivy and Bean series, the Amelia Bedelia series, Romona collection, Magic Tree House series, Amelia Jane books.
A great way to find out which your daughter would enjoy the most is to take her "looking." Make a summer visit to a bookstore and check out these series together. Try looking at the covers to note her interest and then try reading a page or two: the first page plus one from the middle. Your daughter will quickly choose the ones she likes best.
That's a great one! Kids that enjoy the Junie B. Jones series are likely to get a kick out of the Ivy and Bean series by Annie Barrows. We reviewed it in last year's edition of our Third Grade Summer Reading List; you can find the review here: http://www.education.com/magazine/article/third-grade-summer-reading-list/?page=2 . It's about seven-year-old female best friends, and it's supposed to be quite funny!
Another one that comes to mind is one that I read for this year's Second Grade Summer Reading List (http://www.education.com/magazine/article/second-grade-summer-reading-list/) called the Sisters 8 by Lauren Baratz-Logsted (and her husband and her daughter!). Because an eight-year-old helped write it, it's filled with kid-friendly dialogue. It's also a great one to share with a child, because I can personally attest that it's funny for adults, too! :)
I'm also including a link to our full Summer Reading portal. It contains lists by grade, reading recommendations for specific themes, and fun reading activities like illustrating a famous book and starting a kids' book club.
