What do you do after the world has ended? After an influenza strain with a mortality rate of 99.9% sweeps across the world, two survivors, White teens Jamie and Andrew, are brought together by happenstance after Andrew's leg is caught in an abandoned bear trap and Jamie takes pity, welcoming him into his cabin. A promise of potential help from overseas sets the new pair off on a trek from Pennsylvania to Ronald Reagan National Airport in Washington, D.C., and beyond. Along the way, their encounters with different survivors test and strengthen their resolve and their bonds. The narrative, alternating between Andrew's and Jamie's first-person perspectives, is successful at relaying both teens' reasons for making the journey; the story develops organically. Hints to big reveals are subtly scattered throughout, which should successfully hold curious readers' attention: Many will be white knuckled as the twists and turns slowly unfold along with the boys' romance. Those looking to escape the gloom and doom of Covid-19 news may shy away from the topic of a pandemic-driven apocalypse, but that would be a shame because this story delivers. Book clubs and discussion groups will have a lot to dig into, especially as the backstory of Andrew and a mysterious family, the Fosters, slowly unfolds. A haunting story that's sure to delight (and terrify). Readers will find this infectious; highly recommended. (Post-apocalyptic adventure. 12-18) Copyright (c) Kirkus Reviews, used with permission.
