It's not a force in the Newtonian sense, in that no work is done on a falling body. Gravity converts potential energy into kinetic energy, and when the latter is dissipated, you're left with a mass deficit. However if you look on the Einstein digital papers there's plenty of mentions of gravitational force, so IMHO one should be pedantic about this.
As for how gravity actually works, I think it's fairly straightforward. See this post where I attempted to explain it in easy-reading terms.
