Eren Dogan is an electrical and electronics engineer and graduate researcher whose working life is spent on IoT systems, PCB design, robotics, and embedded hardware — and whose writing life is spent on the same problems, approached from a different angle.

The Inspector Rourke stories are the product of that lifelong fascination.

Every book published under Blacktree Press is written to work on at least two levels simultaneously. The fiction has to function as fiction first. The technical material has to be accurate enough to matter. If either condition fails, the book doesn't ship.
