She's 7, almost 8, but we live in another country and she is educated in another language, so she's much stronger in reading that language and she is probably less proficient in reading English than an average 7 year old in the UK. She can read English but she's just at a lower level with it. Something has clicked recently and she's just started reading a lot more independently so I want to encourage her to read in English, too, but we don't own much between the preschooler picture books and more complex chapter books that I have saved from my own childhood.
She's on about the level of the Isadora Moon and Bad Kitty books in her other language, but I'm not sure she would be quite up to them in English (though I haven't seen the English versions).
So do you have any recommendations that would suit a 7 year old in maturity but maybe a bit easier to read than a lot of 7 year olds would be reading in the UK?
