Fabulous middle grade novel with a great concept of being able to 'wander' within your favourite book. Main character Tilly is 11 but this would be easily accessible for chidlren 8+. Lots of references to other books (including lots of classics) that might be good to continue onto once you've finished with this one. Nice representation in Oskar, who is dyslexic but also loves books but just tends to listen to them instead.
