From the author of the Orange New Writers shortlisted THE BOOK OF FIRES

An extraordinarily evocative story of obsession, love and secrets.

1565. Across Europe, a new era of natural science is dawning. In a remote, damp corner of Somerset, an unlikely pioneer is working to change the course of English botany. Passionate, private, meticulous - Henry Lyte has begun to neglect his other responsibilities in the pursuit of knowledge. This has happened before, with disastrous results.

Married again after the tragic death of his first wife Anys, Henry tries to forget the past, absorbed by his scholarly translation of a Dutch 'Herbal' and by the intricate herb garden he is planting, with a Knot at its heart.

Yet beneath the surface he is uneasy, and as the garden begins to flourish, old family troubles start to worm their way up towards the light. Here, on the edge of the fertile wetlands that his new wife Frances fears so much, Henry is accustomed to the peril of flood.

But when the unexpected death of his father unleashes the malevolence of his stepmother Joan Young, he is not prepared for this new threat that could destroy everything he has come to love...
