What had started out as just another research project developed into something unforeseen. A time-traveler appears to have been stranded in the past and might have asked for rescue. Bruce Pocock discovers, while the past is immutable and the future unknowable, that there may be a way to manipulate cause and effect and remove the element of time from the sequence altogether. When it appears that the stranded time-traveler might be Bruce himself, the temporal linearity of cause and effect comes into question. Sterling Sprightly, the preeminent scientist, joins Bruce in an adventure through time that will make one wonder whether that which has already occurred is due to what is about to happen.
