Finished the series last year but since then I've been looking for something like it, if you haven't read it before read it! Really suggest it.
But back to topic, the series follows a guy named "John Corey" (obviously) and he had like a lot of jobs, he's originally a detective for the NYPD that went to Investigate Plum Island, I forgot most of the details but I know I enjoyed it because I still have the whole collection in my bookshelf, any help?
