For my Alaska experience (5 days until I leave - woohoo!) I'm looking for a list of crime fiction books suitable for children of all ages (from 5-18). I'm going to be speaking to about 20 classes ranging in age. Does anyone have any ideas for good books or short stories (together with the suitable age range if possible!) I've got some sugestions from the internet, but would MUCH rather have personal recommendations. All ideas gratefully accepted - thank you very much.
