His engaging plots, featuring multiple storylines, have earned him a reputation for creating 'unputdownable' stories. Ryan's diverse life experiences deeply inform his writing. After receiving a military degree, he served as an officer for seven years until a crippling back injury forced a career change.

His career path then led him to another country where he worked as an IT project manager, before finally pursuing his lifelong dream of becoming a writer in 2014.
