Lexham Press is delighted to introduce an expanded edition of the bestselling title The Unseen Realm by the late Michael S. Heiser, releasing on October 1, 2025 in celebration of the book’s tenth anniversary. This new edition includes additional content from Heiser and features an exceptionally beautiful and unique hardcover that will enhance any bookshelf.
The expanded content is drawn from a companion website that Heiser created around the publication of The Unseen Realm, curated, edited and folded into the book in sidebars and appendices. In this content, Heiser reflects on the book’s content and further develops it.
First published in 2015, the bestselling The Unseen Realm has sold nearly 500,000 across all formats and interest has not waned in the decade since. In the book, Heiser recovers the ancient supernatural worldview of the Bible. Rather than avoiding the strange things in the Bible, Heiser hones in on them and shows how they matter to the work of Jesus. Regarding the book, John Goldingay, senior professor of Old Testament at Fuller Theological Seminary said, “How was it possible that I had never seen that before? Heiser’s survey of the complex reality of the supernatural world as the Scriptures portray it covers a subject that is strangely sidestepped.” Heiser’s writings and teachings continue to surprise and delight his growing fanbase.
Lexham Press presents this new edition to honor the enduring value of Heiser’s work and legacy, reward his readers, and draw in new ones.
The Unseen Realm (Expanded Edition): Discovering the Supernatural World of the Bible publishes October 1, 2025.
