Actor Kevin Costner has signed a book deal with Simon & Schuster’s Atria Books imprint for an adventure series. It begins with The Explorers Guild, Volume One: Passage to Shambhala in 2014. The book is aimed at a broad group of readers, ranging from “young adult to more mature mystery and adventure enthusiasts.”

Writer and art director Jon Baird (pictured, left) also worked on the project with Costner (middle), which will be illustrated by Rick Ross (right). Rob Weisbach and Fonda Snyder at Rob Weisbach Creative Management negotiated the deal with publisher Judith Curr. Atria senior editor Sarah Durand and assistant editor Daniel Loedel will edit the book.

Here’s more from the release: “Behind the staid rooms of an old world gentlemen’s club operates a darker, more mysterious organization: The Explorers Guild, a clandestine group of adventurers who seek out the places where light gives way to shadow and reason is usurped by myth … Set against the backdrop of World War I, with Western Civilization spiraling into chaos, the first installment in The Explorers Guild series, A Passage to Shambhala, concerns the Guild’s quest to find Shambhala, the golden city of Buddhist myth. Each member is driven toward the City for a different reason: one believes that finding it will save his brother’s life; another hopes that it will reveal a path to spiritual enlightenment. Some believe the power of the city can be used to restore peace, while others are certain that Shambhala is responsible for bringing mankind to the brink of apocalypse.”
