Hundreds of kilometers above Tokyo orbits the ParaSOL science facility, connected to terra firma by a massive space elevator, together two incredible feats of engineering and international cooperation. But when the subdued kaiju Rodan and Ebirah arrive at the lab’s mysterious Section X, all of that threatens to come crashing down—literally—when the pair escape their confines and tear into each other. With the two titans locked in battle and plummeting to Earth down the space elevator shaft, it’s up to a team of scientists to stop them before their velocity is truly terminal—for them and for humanity.
