What if you had access to a “Temporal Imaging Machine” and could send a male contraceptive back in time to a village in Austria in June 1888, to prevent the birth of Adolf Hitler? This would be a good outcome, right? What could go wrong? This inventive novel shows that the Law of Unintended Consequences is diabolically operative and so history should not be tampered with. Thanks Amy for this recommendation. Although sometimes Fry’s writing is too cute, this is a very entertaining book.
