Spoiler: they do not make it, the first thread falls before you're ready. How to solve the problem? Deus Ex Machina, kite can travel through time. So you can go back a month in the time to visit yourself and say what you want to do because just will not work! In addition, you can thread now fight in the past, that has always enough resources.
Thus any logic of action is destroyed, everything is paradoxical. That took away any joy to the book.
In addition to the substantive deficiencies made me very intently and the writing style. The author used occasionally a very surprising sentence structure with unconventional choice of words. Although one can find most of these words in better equip dictionaries that helps often not, because none of the meanings given in the context give any sense.
Thus, so the book is good neither to learn English even for entertainment. I have sold off many years ago at a flea market.
