After serving in the United States Army, Aaron Walker, Sr. attended college where he graduated with honors, receiving a Bachelor of Science degree in Game Software Development.

Aspiring to become a writer, Aaron learned the art of screenwriting and storytelling from award-winning writer, producer, published author, and Science Fiction guru: Larry Brody (Star Trek TNG, Star Trek Voyager, HBO’s Spawn the Animated Series).

Aaron’s first teleplay: CARGO (upon which Cargo 3120 is based, a concept he co-created with Daymond C. Roman and Lloyd Walker Jr.), placed as a finalist in the TVWriter.com 2012 People's Pilot competition.

The following year the pilot episode of Cargo would once again, along with Episode 2 (co-written with Daymond C. Roman) place as finalists in the People's Pilot competition. With the positive reception of the concept, he decided to tell the story of Cargo 3120 as a series of novels.

Having been a fan of Science Fiction since he was a child, Aaron hopes to one day make his mark on the genre.

Cargo 3120: Ties that Bind received an Honorable Mention at the 2022 Beach Book Festival and the 2022 San Francisco Book Festival.
