Query: don't read the library of congress info

It's a shame that I accidentally read the library of congress info in the beginning of the book, because some of the major plot points which are carefully and gradually revealed are spelled out right there in a few terse words. Otherwise, it's an excellent book with a few relatively minor plot flaws which are quickly evident to anyone who can think critically about the finer points of the plot.
