The Earthcore camp has been wiped out. Only a handful of survivors remain on the surface. Kayla Meyers is one of those survivors, but who else remains alive? And what will Kayla do to them? And far beneath Funeral Mountain, another group is about to begin a desperate fight for life. Trapped three miles below ground, where rocks are so hot they burn bare skin, Connell, Veronica, Sanji, Bertha, Mack, and O’Doyle are cut off, with no hope for rescue. Are they already as good as dead and standing in their tomb?
