First off this manga series is done by Clamp and it shows. Its typical clamp style a cute girl trying to give her very best in a difficult situation. The lead character Misaki Suzuhara is very much like Sakura from card captors. She small and puny yet her heart and determination are so strong that she accomplishes great things. The manga series though is printed by tokyopop so its read from the back forward which is cool.
The plot is very basic, and why shouldnt it be? There doesnt have to be a long and twisty plot to keep people entertained. Misaki moved to tokyo to attend a school there and while shes there she discovers angelic layer, a table top game where players (known as deuses) battle one another using small dolls which they customise so each one is individual to the player, and basically thats it. Misaki makes a doll (named hikaru from magic knight rayearth) and battles it right up to the national tournament. The end. Its sweet and lovely to read, and Misaki is just so caring and cute that you cant help being happy when things go her way, and sad when they dont.
One thing I love about this series (which is 5 books long) is at the beginning of each book there are newpaper articles, most of which relate to angelic layer but some of the side lined articles are chobits/cardcaptor/rayearth in fact all clamp related. Its pretty clever as they tie in other clamp productions into the angelic layer theme, which i thought was utterly charming, and in my opinon charm is what Clamp does best.
If you want something light and happy to read then I couldn't recommend anything better than Angelic Layer
