In the shadows of modern Britain, the Crown hides Rosewood-the last sanctuary of the Fae. Only those with Spoken Rose clearance may speak its name. Fae agent Siarl has survived memory wipes, iron poison, and betrayal. When a reckless new recruit triggers an old enemy, Siarl must reclaim the poisoned isle before the Fallen tears open the gateway to the Fae Fel. With iron assassins hunting them, a Breathless ally of uncertain loyalty, and the constant threat of Sanction-being sectioned in an asylum and discredited forever-Siarl faces an impossible choice: protect the Rosewood at all costs, or watch two worlds burn. Some secrets are spoken only under the rose. Some truths cost your freedom... or your life.
