When Sakura opens a book in her father's library, she accidentally frees the Guardian of the Seal and now must collect the escaped Clow Cards. Cue the cutest, most tooth-achingly sweet adventure ever! Given that the target audience for this is kids, older readers may feel a little disenchanted with how easily everything is solved. And not to mention, this is volume where things get weird. 
 Sakura is a fourth grader. One of her classmates is engaged to their teacher. Sakura's mother was a student when she married Sakura's father -- who was her teacher. Tomoyo's mom is obsessed with making Sakura look like her mother -- whom she was in love with. Tomoyo is in love with Sakura, there's definitely something in the air between Touya and Yukito... it's total hormonal insanity. 
 That said, I like how CLAMP didn't stereotype all of these LGBT crushes -- unlike a lot of literature, which follows stereotypes of how gays/lesbians should act -- these characters felt more like people to me. So three stars for this reason, even though I want to demote it to two for all the weird romance. I just can't get over all the weird student/teacher relationships. Eep!
