  EDIT: removed IDW's Transformers

The Hilda series by Luke Pearson is really great. I think Hilda and the Troll is the first one, but I don't think they necessarily need to be read in order.

Also, all the Raina Telgemeier. She has Smile, Sisters, Drama, and Ghosts, as well as graphic novel versions of the Babysitter's Club books that are fantastic. And Roller Girl by Victoria Jamieson.

Everything, everything, everything Frozen.

I second the suggestion for art supplies and books. Put it together and go for a doodle book, a kind of middle grade coloring book.

Some great cheap ideas that you can package all together (the more gifts for a little girl, the better)

• Doodle Diary - $9
  
• Frozen Anna Doll - $13
  
• Both the Anna & Elsa plush dolls - $20
  
• Sisters, it's the companion book to Smile (so either or both). These are graphic novels for girls, I work in publishing and they are INSANELY popular for this age range - $7
  
• American Girl Scrapbook Kit (If it has American Girl on it, fourth graders flock) - $7
  
• It's All About Us - Personal Questions Quiz (like a paperbound Buzzfeed) - $12
  
• Madlibs - $3
  
• Mini American Girl Doll - $21
  
• Matching American Girl Novel - $8
  
  Hope this helps!
