I'm looking for suitable books for my DD for her birthday. She's on the penultimate Harry Potter and also reading the Hobbit. Books that are aimed at 13 years olds don't always seem suitable for a younger child so would appreciate any recommendations. She's not a girly girl, also likes Roald Dahl, David Walliams and Wimpy Kid books, but not sure if she's enjoy books actually aimed at boys iyswim. thanks!
