  We present a model of gravity based on spontaneous Lorentz symmetry breaking.
We start from a model with spontaneously broken symmetries for a massless
2-tensor with a linear kinetic term and a nonderivative potential, which is
shown to be equivalent to linearized general relativity, with the
Nambu-Goldstone (NG) bosons playing the role of the gravitons. We apply a
bootstrap procedure to the model based on the principle of consistent coupling
to the total energy energy-momentum tensor. Demanding consistent application of
the bootstrap to the potential term severely restricts the form of the latter.
Nevertheless, suitable potentials exists that permit stable vacua. It is shown
that the resulting model is equivalent, at low energy, to General Relativity in
a fixed gauge.
