Publisher's Summary

Harper McKenzie wakes to the worse possible day: her 18-year-old son has vanished from her Manhattan apartment without trace.

Worse, no-one knows what she’s talking about. 

No-one thinks she had a son. 


Has she lost her grip on reality?

Or has the world shifted in a terrifying and unpredictable way?

The Effect is a taut psychological thriller that challenges everything we thought was real, as Harper’s quest to find her son pushes her to the very edge of reason.
