AbstractSpecial gravity refers to interacting theories of massless gravitons in Minkowski space-time which are invariant under the abelian gauge invariance h(ab) -> h(ab) + partial derivative((a chi b)) only. In this article we determine the most general form of special gravity free of Ostrogradski ghosts, meaning its equation of motion is of at most second order. Together with the recent works, this result could be helpful in formulating proofs of General Relativity as the unique physical theory of self-interacting massless gravitons. We also study how to construct gauge invariant couplings to matter fields.
