Read or Dream

Read or Dream, also called Shin Read or Die, is the sequal to the Read or Die four volume manga. It does not feature Yomiko Readman as the main character, but rather new characters from the Division of Special Operations of the Royal British Library.

From Viz:
Michelle is a romantic daydreamer and hardcore book collector. Maggie is a soft-spoken bookworm who always gets mistaken for a boy. Anita is an athletic tomboy who doesn't have time for reading. Together, they're the Paper Sisters, three very different siblings united by a strange power--the ability to control paper in any way they desire! And from their Hong Kong detective agency, they solve any and all cases involving books!
