Cardcaptor Sakura is not my cup of tea but then again, I'm a bit older than the target audience. As with all Clamp manga, characters are well drawn and super cute. And these stories are all about female empowerment - Sakura always gets her card! - and female protagonist has super powers.
If you've enjoyed the first two books in this series, you will also enjoy this third volume, as it follows the same plot conventions and patterns - this story is just more of the same.
