Bronswood (How It Had To Be, #2)

Welcome to Bronswood. The most prestigious private elementary school in Windwood.
Heather Hartford's life is finally looking up. She's traded an abusive relationship for an affluent second husband with connections and status in the community. His social standing opens Bronswood's great wooden doors for Heather's two kids. The Bronswood PTA royalty have taken Heather under their wings. Her children, Charlie and Theodora, will have every opportunity in life that she herself never had.
But Heather's dream quickly becomes a living nightmare.

When she goes to pick up Charlie from school, Heather's world is upended when his teacher informs her that she picked him up earlier that afternoon. Security camera footage confirms it.

But Heather knows she hasn't picked him up, and she throws herself into an obsessive and dangerous search to find her son. As she sinks deeper into the mystery, she realizes: Charlie isn't the only child who's disappeared.

Heather isn't sure who to trust. Police think her son ran away. Charlie's father is suddenly reappearing in Heather's life. And something sinister is happening inside the walls of Bronswood.

Heather will stop at nothing to save her son. But first she has to find the answer.
Where is Charlie Hartford?
