Posted about this earlier in the year, but it's now in the shops.
A story about chocolate in the usual Charlie and Lola style, looks at growing the beans and making chocolate and buying Fairtrade - complete with a lot of nice stickers, including lots of Fairtrade ones.
Go out and buy one or more. £2 from each sale goes to Comic Relief.

My son says "I think it's a new thing. I liked reading it. I like the stickers."
