Mog!

Bought E a new book in the charity shop but had to sit down and read it myself first...quality control you understand.
Loved it. Cleo to a 'T'.
I've loved all the Judith Kerr books that I've read. She's 94 now and had another the book published just a couple of months ago, amazing.
The 'When Hitler Stole Pink Rabbit' series of her life in prewar Germany and then the UK are a great semi-autobiographical series and really bring the period to life, they were aimed at 10-14 year olds I think. Well worth a look if you don't know them.
But Mog wins hands down!
