The books are fine. Unfortunately I have been trying to change the age group of the books I ordered but trying to get someone to respond has been as to date impossible. As Cratejoy pushes you off to the supplier who has not responded I am stuck with a product I do not need. Until Cratejoy can get the suppler to respond or they step in to resolve I would say I could not recommend them. Maybe they can help but so far..... not!
