Ringer gives herself up to a helicopter patrol knowing that she will be brought back to Vosch, in the hopes that they can save Teacup. Ringer explores a network of caves near the hotel and shoots fellow squad member Teacup, mistaking her for another Silencer. All except Cassie believe that Evan died in the destruction of the camp, so they are mainly concerned with distancing themselves from Vosch and surviving the winter. After the group escapes and destroys Camp Haven, the remaining members of Squad 53 find shelter in an abandoned hotel. The Infinite Sea expands the narrative focus out from Cassie and Ben to include Evan and Ringer. Silencers have increased strength and endurance, but in all other aspects appear to be completely human distinguishing ally from enemy is therefore difficult. The fourth wave, and the main subject of the first book, reveals the existence of “Silencers,” or aliens that take over the body of a human host. The third wave is a plague resembling Ebola, a highly infectious disease causing internal and external bleeding, which is first spread via birds and then by infected humans. In the second wave of the attack, a series of tsunamis again takes a heavy toll on the population, especially those living along the coast. The first attack is an EMP, effectively destroying all of Earth’s technology and instantly decimating half the population. In the first book, also called The 5th Wave, aliens known as “Others” have repeatedly attacked Earth in various waves, attempting to destroy the human population.

The Infinite Sea (2014) is the second book in Rick Yancey’s young adult science fiction trilogy The 5th Wave.
