On July 19, 2032, lawyer Sheffield will open an envelope in Washington, left for storage half a century ago by the famous physicist Hugh Everett. What he finds in the envelope will cause extraordinary and mysterious events. The world may perish. The world can be saved. Which of the worlds? Maybe ours, the world in which we live. Meet the new novel from the classic of the genre Pavel Amnuel - super-hard NF in a fascinating wrapper of a fantastic detective!
