We investigate black brane solutions in asymptotically Lifshitz spacetime in -dimensional Horndeski gravity, which admit a critical exponent fixed at . The cosmological constant depends on z as . We compute the shear viscosity in the -dimensional dual boundary field theory via holographic correspondence. We investigate the violation of the bound for a viscosity to entropy density ratio of at .
