This is a fact: Ryan Summers walked into Three Rivers College and killed thirteen women, then himself.
But no one can say why.
The question is one that cries out to be answered - by Ryan's mother, Moira; by Ishbel, the mother of Abigail, the first victim; and by DI Helen Birch, put in charge of the case on her first day at her new job. But as the tabloids and the media swarm, as the families' secrets come out, as the world searches for someone to blame... the truth seems to vanish.
A stunningly moving novel from an exciting new voice in crime, ALL THE HIDDEN TRUTHS will cause you to question your assumptions about the people you love, and reconsider how the world reacts to tragedy.
