Perfect, by Rachel Joyce, is a really good book and you should read it!
Summer, 1972: In the claustrophobic heat, eleven-year-old Byron and his friend begin ‘Operation Perfect’, a hapless mission to rescue Byron’s mother from impending crisis.
Winter, present day: As frost creeps across the moor, Jim cleans tables in the local café, a solitary figure struggling with OCD. His job is a relief from the rituals that govern his nights.
Little would seem to connect them except that two seconds can change everything.
And if your world can be shattered in an instant, can time also put it right?
