Audiobook narrated by Ray Porter.
This is the last (for now) Bridgeman book and this one enters a somewhat convoluted wibbly-wobbly timey-wimey stuff. Joe is sent to retrieve a focus object which has been inveigled form it’s owner and is in danger of being lost from history. It turns out that there’s an organisation called Extempero which consists of a bunch of billionaires using focus objects for time-tourism. Joe makes a hasty jump to save the day, but it doesn’t turn out well. He has to make another jump to ameliorate the situation, but that one has an even worse outcome, and then he gets the opportunity to change his own timeline again. We go from ancient China to an earthquake in San Francisco – twice. Once again Scarlet makes an appearance to complicate things.
