The thrilling conclusion of The Touchers series!

In "After the Bubbles," oddly shaped bubbles falling from the sky transformed ordinary people into monsters that kill humans just by touching them. Now these yellow creatures roam the Earth, intent on exterminating the few remaining survivors—including teenager Erin Fredericks.

Erin joins the army, a ragtag outfit housed in a nearby office complex, and she and her boyfriend, Blaine, team with other soldiers to destroy the creatures she calls "touchers." But their desperate fight becomes nearly impossible when the monsters sprout wings.

As the army's weapons prove ineffective against flying touchers and the evolving monsters develop new deadly abilities, the situation seems hopeless. How can Erin, Blaine—and the rest of humanity—be saved?
