From New York Times bestselling author AJ Hartley and the imagination of disruptive creator Tom DeLonge comes an electrifying sci-fi thriller that challenges our understanding of time, history, and humanity. Building on their successful collaboration on the acclaimed Sekret Machines franchise, these creative powerhouses deliver a story that combines Hartley's masterful storytelling with DeLonge's specialised knowledge of anomalistic phenomena. Time Rider follows Bowie, an agent from a dystopian future called the Design - a society where humanity is stratified into genetic castes and emotional connections have been engineered away. Sent to 1963 on what he believes is a mission to preserve history, Bowie discovers he's actually part of a conspiracy to manipulate the past. Alongside journalist Sandra Rossi, he races through different time periods uncovering a shocking truth: the Design isn't preventing terrorists from changing history - it's orchestrating historical events to ensure its own existence. As Bowie experiences the raw emotions and connections absent from his sterile future, he begins questioning everything he was programmed to believe. The climax converges on the Kennedy assassination, revealing layers of deception that stretch across time and may involve non-human intelligence. More than a time-travel adventure, this thought-provoking thriller examines totalitarianism, the manipulation of history, and what truly makes us human. Hartley and DeLonge craft a narrative that's both action-packed and philosophically rich, challenging readers to consider how our understanding of the past shapes our future and what parts of ourselves we can never allow to be engineered away. Time Rider is based on the Sinister Forces Trilogy by Peter Levenda.
