Mog in the Dark, by Judith Kerr, Collins Picture Lions, 1986.
Despite having lived in England for a few years during my youth, and then, much later, growing up to be a children's librarian, I wasn't familiar with Mog books. At least I wasn't until last year, and that infamous, glorious Sainsbury advert. I was so in love with Mog from the advert, I had to buy my own Mog the cat. Then my son wanted one. And one thing led to another and to this book.
Even though this book isn't the strongest outing for Mog the cat, my son still loved it. I suspect, however, he will love the ones he is getting for Christmas even more.
