The most powerful blast of cosmic radiation in the Universe is just seconds from slamming into Planet Earth. When a gamma ray burst from two colliding stars hits the atmosphere, the deadly radiation delivers agonizing death and immediately wipes out half the planet. On the other side of the Earth, the Americas face a slower death as ultraviolet radiation and starvation threaten to send the human race into extinction. How will the last remaining humans survive?

For the first time in human history, a volcanic hyper eruption blows through the surface of the Earth. Explosive shock waves tear apart buildings, molten rock slam into cities, and a deafening sound circles the globe. A bad day for Planet Earth gets worse as volcanic gas blocks out sunlight, food chains collapse, and epic famine threatens the very future of mankind.

What if, for the first time in four and a half billion years, the Earth was pulled out of its orbit... sending our planet on a collision course into the Sun. Earth's deadly fall takes 65 days, triggering massive hurricanes, sandstorms and--with temperatures reaching over 200 degrees--a heat wave that kills every last person.
