James P. Sumner began his self-publishing journey in 2013. He's now the author of over 20 titles, and the recipient of numerous writing accolades, including a 2015 Winner of the Kindle Scout program, and the ATAI Best Thriller and Best General Fiction 2017 for this novel, Thicker Than Blood.

His original, fast-paced, and thought-provoking thrillers span three popular series: Adrian Hell, GlobaTech, and Roach.

He has also created a sci-fi series, A Chorus of Stars — a passion project inspired by his life-long love of genre classics like Star Wars and The Expanse. This has brought him to a whole new audience who are already hooked on his work.
