DD was a big fan of the Lottie Brooks book by Katie Kirby. I'm trying to find something similar but having not much luck! I thought of the Georgia Nicholson series but I feel this is maybe a bit too old for her just yet, there's a lot of sex references in it from what I remember, even if it's just to say how gross it is... she's at such an awkward age where everything is either too old or too young, too small or too big!
