Silas Mercer has faced wily boggarts, mad faerie queens and enraged forest spirits.

But can he withstand a daemon who is losing his mind?

Pitch and Sickle are left bruised, battered and reeling after their confrontation with the Verderer.

They have learned a startling truth behind the arrowhead that wounded Silas, a truth that must be taken to the Lady Satine and the Order without delay.

But his encounters in the Forest of Dean have effected Pitch in alarming ways. The daemon's body may have healed but his erratic behaviour and wildly unpredictable temper grow ever more concerning.

Silas owes his life to Pitch. Their experience in the forest has brought them a closeness he could not have imagined possible.

But what can he do for a daemon who is losing his way?

And how long will Silas survive, if he must ride alone?
