After the first wave, only darkness remains. After the second, only the lucky escape. And after the third, only the unlucky survive. After the fourth wave, only one rule applies: Trust no one. Now, it's the dawn of the fifth wave, and on a lonely stretch of highway, Cassie runs from Them. The beings who only look human, who roam the countryside killing anyone they see. Who have scattered Earth's last survivors. To stay alone is to stay alive, Cassie believes, until she meets Evan Walker. Beguiling and mysterious, Evan Walker may be Cassie's only hope for rescuing her brother - or even saving herself.

When sun flares hit the Earth, intense heat, toxic radiation and flooding followed, wiping out much of the human race. Those who survived live in basic communities in the mountains, hunting for food. For Mark and his friends, surviving is difficult, and then an enemy arrives, infecting people with a highly contagious virus. Thousands die, and the virus is spreading. Worse, it's mutating, and people are going crazy. It's up to Mark and his friends to find the enemy - and a cure - before the Flare infects them all.

Already a prisoner to her own nation, now she has been sentenced to death for her crimes. But one decision could save her life. To enter the kingdom of Patrus, where men rule and women submit.

When Ruby woke up on her 10th birthday, something about her had changed. Something frightening enough to make her parents lock her in the garage and call the police. Something that got her sent to Thurmond, a brutal government “rehabilitation camp.” She might have survived the mysterious disease that had killed most of America’s children, but she and the others emerged with something far worse: frightening abilities they could not control.

The mining ship El Cavador is far out from Earth, in the deeps of the Kuiper Belt, beyond Pluto. Other mining ships, and the families that live on them, are few and far between this far out. So when El Cavador’s telescopes pick up a fast-moving object coming in-system, it’s hard to know what to make of it. It’s massive and moving at a significant fraction of the speed of light.

El Cavador has other problems. Their systems are old and failing. The family is getting too big for the ship. There are claim-jumping corporate ships bringing Asteroid Belt tactics to the Kuiper Belt.
