AVOID this company, expensive ebooks that are never yours, but RENTED !!!

I'd recommend you never ever buy digital books from this company. For the past number of years I've been purchasing ebooks for my daughter at High School, in the belief that she would always have them. Today is her last final exam and discovered that she'll never be able to access them again - not even for reference/revision should she go to Uni in a year or two. To all other parents, BUY THE HARDCOVER BOOKS, at least you'll have them forever, and can always resell them as 2nd handbooks if you choose. This company is a CON !
