Ms 15 was told that she needed to start reading some French books to improve further in her study of the French Language. This makes a lot of sense to me. Reading is the basis of her large English vocabulary and her grasp of the finer points of the language.
She found the French edition of the fourth Harry Potter in the school library and after a long time (for her) she is near the end. Harry Potter is a good choice. She knows the books really well and they are amusing and interesting but not too difficult to read (they are kids books after all). Now she needs the rest and they are hard to find.
So off to the Amazon Kindle store, and then onto the Pottermore Store and finally we have the first three, in French, on the Kindle. Happy.
