When teacher Sarah Martin returns home, she expects to spend the summer catching up with her foster mother Mim. But Mim is stuck in Brockburn General after a knee operation—and something isn’t right on the wards.

The daily routine hides a dark secret. Cash is disappearing. Vulnerable patients are being preyed upon. But when fellow visitor Petra Walker vanishes without trace, Sarah realises the hospital’s problems are far more deadly than anyone imagines.

Trapped in a labyrinth of ancient wards and shadowy corridors, Sarah must uncover the truth before more lives are lost. But the closer she gets, the more she learns: in this hospital, danger doesn’t come from disease—it comes from those there to protect you.

A heart-stopping medical thriller packed with tension and twists, Ward Zero is perfect for fans of Tess Gerritsen, Karin Slaughter, and Shari Lapena.
