I don't think so. Usually, such news would be widely reported if there was a new novel by Cormac McCarthy in March 2019. But you can do a search on major book platforms or literary news outlets to be sure.
In his c - novels, one common theme is the exploration of the self. For example, in 'Remainder', the protagonist is constantly trying to reconstruct his sense of self through re - enacting past events. Another theme is the relationship between humans and their environment, both physical and cultural.
We don't know when Cormac McCarthy's new novel will be released. There are no pre - announcements, no hints from the author or publishers. His writing process is often a mystery, and until there are some clear signs of a new work nearing completion, such as a publisher's announcement or the author himself talking about it, it's completely uncertain when, or even if, a new novel will be released.
