i bought 42 (6 series) for my girl (7 yrs old), plus a few Special Editions. (have ordered the #7series but not received yet)
Firstly, many classmates of her school read this series so she is very happy to have the full set eventhough she's still reading slowly. (but at least she has the motivation to read on)
At first she found this more difficult than the colour stories read before but I accompany her / read to her for the 1st story & then she reads the rest all by herself. Girls at their age love fairies or beautiful things very much & the words are in fact easy to understand & the stories are also simple & interesting.
my girl loves reading the series. She is 5 yrs (almost 6) and she can read 1-2 books a day. I haven't read them so no ideas at all, but I think it must be very interesting fairy story.
I heard that some big bookstores got it already, but no discount. I have ordered from the web & got 15% off, they said next shipment will got it. (if u have other books preorder & reach $1000, then 20% off, $2000 will have 25% off!)
