Cho Hye Yeon: Creative life and death, volume 1Nice collection of life and death problems to train reading skills. Level: dan players. The problems need often a number of diagrams to explain all the errors you can make:)
Miss Cho, who is unusually talented, reaching pro status before she was 12, has a popular blog on the internet on go: http://loveku.livejournal.com.
Creative life and death, volume 2Volume is like volume 1, but the problems are slightly more difficult.
