A Bargain for Frances by Russell Hoban, for the #1970Club

Frances the Badger is best known for refusing to go to sleep (Bedtime for Frances), being unadventurous about food (Bread and Jam for Frances), disgruntled about her new sibling (A Baby Sister for Frances), exploring friendship (Best Friends for Frances) and upset that it is not her birthday (A Birthday for Frances) but in this book she deals with something familiar to at least some of us – a sneaky friend.
