Why has the Japanese haiku poet Buck-Teeth stopped writing after a certain lunar eclipse, and what can be done to help him recover his inspiration? When an evil ninja slinks into the pages intent on murder, we find that writer's block is no mere academic problem but a grave matter with lives and poetry hanging in the balance. This isn't exactly a sequel to 'Haiku Guy'; it's more like a new peek into the lives of the same characters: the village poet, Buck-Teeth; the cruel courtesan, Lady Plum; the daimyo-turned-hermit, Lord Kaga; the color-coded Poets in Green, Black, and White (Mido, Kuro, Shiro); haiku master Cup-of-Tea; and the narrator's Thursday afternoon writing group, commenting on, and entering into, the unfolding plot.
