Perfect by Rachel Joyce
Byron Hemmings is a clever boy with an equally clever best friend James Lowe. When they hear about adding an extra two seconds, the idea astounds them both. But then Byron notices his watch moving backwards at the exact time the accident happened, and nothing will ever be the same. Together, these boys attempt to put things right during that spring and summer of 1972. 40 years later, the mental institution that Jim has been in and out of since he was 16 is closing its doors. Now Jim has to figure out how to live in the real world, and how to protect it from any harm he might cause. In this fascinating story, told in chapters that alternate between 1972 and 40 years later, Rachel Joyce (The Unlikely Pilgrimage of Harold Fry) once again takes us on a uniquely personal journey in her second novel "Perfect".
