Perfect by Rachel Joyce
In 1972 scientists discovered that the atomic clock was “off” and an extra two seconds needed to be added to correct time. Twelve year old best friends James and Byron are deeply disturbed by the idea that time can be altered so easily. Byron in particular is very concerned about when the two seconds will be added, especially when he sees his watch jump as his mother is driving him and his sister to school. As those seconds are added he sees the girl on the red bicycle out of the corner of his eye. He knows they have hit her with their car, just as he knows that his mother has no idea what she has just done. Those two seconds will change the lives of everyone in the story for their lifetimes.
This is a slow building book with two storylines set in the past and the present. It is amazing to see how much one event, two seconds, impacts so many lives. The story, the interconnectedness of all the events and consequences, unfolded little by little making sure the cause and effect were evident, until you realize that misassumptions have been made. (Can’t tell you what I mean, there is a whopper at the ending.) A good choice on audiobook.
