Triangulum: Earth on Fire continues the store from Triangulum: Battle for Earth as the war-ravaged planet moves forward to rebuild while seeking revenge for the unprovoked attack by the AshDorm. Emma Henderson is given credit for saving the world from the alien invaders and made head of the World Security Organization Commission, known as WSOC. Their focus is reclaiming the Dead Zones, areas destroyed during the alien war. Soon old hate-filled rhetoric returns in the media and from WSOC members. War breaks out as China, Russian, and factions in the Middle East seize an opportunity to expand their counties at the expense of others. With the world in chaos, Emma and her team struggled against the tide of World War III. Can Emma and the RAI army build up enough forces to stop the invasion of North American or will all be lost as China and Russia flex their military might?
