Unlike her drama-queen twin sister, Charlie Franks is always fine. At least she is until she has to start a new school, finds out she can't ride her new horse, and gets told that her Mum has something totally weird wrong with her. Charlie's not A-OK. Not at all. And she can't see how things are ever going to get better.'Charlie Franks is A-OK' is the sequel to 'Love and Muddy Puddles' and the second book in the Coco and Charlie Franks series.
