Lola and Lotta's friendship is put to the test! Lola's bestest best friend Lotta has a new coat, which was an extra-special gift from her granny. It is the fluffiest, softest, most loveliest coat Lola has EVER seen and she absolutely must borrow it. Lotta says okay, but only as long as Lola promises to not wear it in the rain or spill food on it or get it dirty. Will Lola be able to keep her promise? With Lauren Child's signature wit and verve, this new Charlie and Lola adventure shows how important honesty is in bestest-best friendships.
