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 specialized knowledge of extraordinary phenomena.

Synopsis:

In a future where history itself is weaponized, one agent must choose between the sterile “perfection” of his engineered society and the messy humanity of the past he was sent to manipulate.

Time Rider follows Bowie, an agent from a post-democracy future state known as the Design—where humanity is stratified into genetic castes, and emotional connections have been engineered away. Sent to 1963 on a mission to preserve a lynchpin moment of history from temporal terrorists: the assassination of the American President. Baffled by what he finds in Dallas, Bowie soon discovers that something far more strange and sinister is at work. Alongside journalist Sandra Rossi, he races across time to unveil a shocking picture of hidden agendas and extremist ideologies, that force him to reevaluate the world he came from and the future of humanity itself before they’re both lost to time.

More than a time-travel adventure, this thought-provoking thriller examines totalitarianism, the manipulation of history as a means of ideological indoctrination, and what it is that 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
