J.T. Siemens grew up in Vernon, BC, and moved to Vancouver to pursue a career as a personal trainer. A longstanding love of books and movies led him to study screenwriting and creative writing, and he has been published in Mystery Weekly, Down in the Dirt, CC&D, and Vancouver Magazine.

After a murder occurred outside his workplace, he was inspired to write a novel, To Those Who Killed Me, which was nominated for the Arthur Ellis Unhanged Award. The novel introduces the character of Sloane Donovan and is the first in a series about a bipolar ex-cop turned PI. He recently completed the second Sloane Donovan novel, The Call of the Void. He lives in Vancouver's West End with his girlfriend and two cats.
