  We construct new black brane solutions in $U(1)$ gauged ${\cal N}=2$
supergravity with a general cubic prepotential, which have entropy density
$s\sim T^{1/3}$ as $T \rightarrow 0$ and thus satisfy the Nernst Law. By using
the real formulation of special geometry, we are able to obtain analytical
solutions in closed form as functions of two parameters, the temperature $T$
and the chemical potential $\mu$. Our solutions interpolate between
hyperscaling violating Lifshitz geometries with $(z,\theta)=(0,2)$ at the
horizon and $(z,\theta)=(1,-1)$ at infinity. In the zero temperature limit,
where the entropy density goes to zero, we recover the extremal Nernst branes
of Barisch et al, and the parameters of the near horizon geometry change to
$(z,\theta)=(3,1)$.
