Silvercloak, L.K. Steven's dark fantasy novel published in 2025, has been championed as an ideal candidate for streaming adaptation, combining the undercover intrigue of the crime thriller The Departed with the magical crime elements of Leigh Bardugo's Six of Crows. The novel marks Steven's transition from young adult to adult fantasy, and with its newly released sequel Turncloak already expanding the saga, it offers sufficient material for a multi-season series that would fill a unique niche by blending fantasy and crime drama.

The story follows Saffron Killoran, a mage seeking revenge for her parents' murder by the criminal Bloodmoon organisation, who infiltrates the group as an undercover agent after being publicly disgraced from the elite Silvercloak Academy. What distinguishes Silvercloak is its distinctive magic system in which all magical abilities are powered by pleasure or pain, creating an indulgent society where mages employ creative tactics in combat. The world-building extends beyond the crime plot to encompass ancient prophecies, dragon lore, forbidden time magic, and star-crossed romance, creating a complex and morally nuanced setting ripe for adaptation with surprising realism despite its fantastical elements.
