DD is a massive reader - she's 9.5 - she enjoys having a series to read. She likes mystery/spy type books but is open to all sorts. She didn't like the lemony snickett when we tried that unfortunately. Recent series that she enjoyed are:
Murder most unladylike
Sinclair Mysteries and the Taylor & Rose mysteries by Katherine Woodfine
Ruby Redfort - she's on the last book in this series and has really loved it.
Harry Potter
Any ideas for what she could try next?
