Wilson's 100 Cupboards trilogy, published by Yearling, is the story of Henry York, a boy who finds his way to other worlds through the cupboards in the attic of his uncle's Kansas house. Wilson's mythical milieu includes significant Arthurian influence, both from Geoffrey of Monmouth (Wilson has a character by that name) and Spencer's Faerie Queene. Wilson is also admittedly influenced by Scottish fairy tales from Robert Kirk and Sir Walter Scott. Feature film rights to the trilogy have been acquired by Beloved Pictures.

The first volume in another Wilson series, The Ashtown Burials, has an expected publication date of 2010. Three Smiths is the story of siblings Cyrus, Antigone, and Daniel, who become involved in a secret society after their parents' hotel burns down.

Film

Wilson has been tapped to write the screenplay for a film adaptation of C. S. Lewis's The Great Divorce, slated for release in 2011.

Other writings

Wilson's short fiction and prose have been published in Credenda/Agenda, the Chattahoochee Review, the Esquire napkin project, Christianity Today, and Books & Culture.

In 2005, Wilson announced in Books & Culture magazine that he had made a near-duplicate of the Shroud of Turin image by exposing dark linen to the sun for ten days under a sheet of glass on which a positive mask had been painted, and in doing so, "caused some uproar in the Shroud of Turin world."
