My DD (now 12) has always had a giant list of books she wanted also - still does. She reads far above grade level, but that doesn't mean that everything she read was in that range. Once you hit a certain point, even some classic books will be under your range, since it is based on the breadth of the book's vocabulary.
At any rate, some of her favorites in 5th grade were...
• Twilight (she read New Moon and Eclipse in 6th grade, but we have banned Breaking Dawn until she is a bit older)
• The Beacon Street Girls series
• Anne of Green Gables series
• series that begins with Among the Hidden (don't know the series name, but it also has Among the Brave, Among the Free, etc.)
5th grade was also when she started to be interested in necklaces, bracelets and fancy hair things. She also started to show some interest on cooking so we got her a kid's cookbook (Williams-Sonoma, I think) with recipes she could do without help.
Have fun!
