Due to the amount of toys they have and don't look after my boys (nearly 9 and 11.5) are getting mainly books for Christmas this year...
They are both of a similar reading level and are into Beast Quest at the moment but have also been reading Diary of a Wimpy Kid, some Jeremy Strong stuff, Roald Dahl, ... According to Humphrey and DS2 likes Horrid Henry.
I'm thinking fantasy stuff and funny stuff is probably what they like the most although I might get some Michael Morpurgo stuff too. Any suggestions for more good reads?
