  We present a higher codimension generalization of the DGP scenario which,
unlike previous attempts, is free of ghost instabilities. The 4D propagator is
made regular by embedding our visible 3-brane within a 4-brane, each with their
own induced gravity terms, in a flat 6D bulk. The model is ghost-free if the
tension on the 3-brane is larger than a certain critical value, while the
induced metric remains flat. The gravitational force law `cascades' from a 6D
behavior at the largest distances followed by a 5D and finally a 4D regime at
the shortest scales.
