This is my first post, so bear with me!
I've just come from shopping with my son at WH Smith, Mansfield and when we got to the counter, the lady asked if my son wanted some free books. Obviously, he said yes so she handed over :
Horrible Science - Painful Poison
Horrible Science - Ugly Bugs
Horrible Science - Evil Inventions
Horrible Science - Space, Stars and Slimy Aliens
Author - Nick Arnold
She didn't mention why she was giving them away but it looks like it something to do with The Daily Telegraph, though I haven't found anything online. Not sure either if its only for today or while stocks last.
These are really great books for older kids, by the same author as Horrible Histories.
