So reads the backs of the books in this action series. St. Vincent's first encounter with Mero was a fun one - driving in the desert of California in his Ferrari, he notices a pair of headlights gaining on him. Being a racer and having an awesome car in which he is speeding, he knows that was impossible. He soon learns more impossible things and his life is never the same again as he is recruited into Mero and taught to use the gifts he'd always have in defense of a needy world.
St. Vincent loves adventure and he gets a ton of it with Mero. He also loves the ladies and he gets to know a lot of them, both good guys and bad guys. He also finds that he just seems to get better and better and, while his ego grows to be a bit much, the excitement and the dangers grow right along with it.
Along with his ego growing, so grows the strangeness of the cases as the subjects fall full-force into the realm of science fiction. ESP, telepathy, mind-control, and all other facets of the paranormal come into play in one manner or another. St. Vincent finds he not only has to be one step ahead of the bad guys, he has to be one thought ahead of them as well.
