Called Sekret Machines, the transmedia series will feature new music from Angels & Airwaves, fiction and non-fiction books, as well as a documentary. Everything officially kicks off on April 5th with the release of a 704-page hardcover novel, Sekret Machines Book 1: Chasing Shadows, the first in a trilogy that DeLonge co-wrote with author A.J. Hartley.

Discussing the book's subject matter, DeLonge said in the press release, "I wanted to tackle the subject of Unidentified Aerial Phenomena because it seems so unbelievable."
