You’ve probably seen the YouTube clip - two friends being reunited with the lion they raised from cubhood until it was too big for their tiny London flat - now you can find out the story behind it in Christian the Lion.

This is the story of John and Ace and their pet lion Christian, adapted for younger readers aged 8-12 years. If you love animals, or enjoyed reading Marley and Me, then you are guaranteed to enjoy this book which is both funny and sad. It does a very good job of describing how a curious lion might feel in a big city, and when put in the wild with other lions for the first time. There are lots of colour photos as well; my favourite one shows Christian drinking out of the toilet! The only thing I’m puzzled about - why were there lions for sale in Harrods in the first place?!
