Homeland meets Marie Lu’s Legend in the explosive sequel to Blackout, which #1 New York Times bestselling author Ally Condie called “a thrilling combination of Wells’s trademark twists and terror.

Thirteen-year-old Quinn and her friends can't believe their luck when spring break is extended an extra two weeks--even if it's because of some virus. But when the impact of the worldwide COVID-19 pandemic becomes apparent, everyone, not just the students, has to learn to adjust to their new reality. Quinn's father is an ER doctor and has to self-isolate to protect his family from the virus. Isaac's mother is the chief of police and now has to enforce new physical-distancing bylaws. Reese can't visit her grandmother in her care home anymore. And their entire school has moved to online classes. Sacrifices have to be made to keep everyone safe, but there's more to life than rules and scary news reports. In an effort to find some good in all this uncertainty, Quinn comes up with an idea that she hopes will bring the entire community together.

Engrossing true stories of the pioneers of epidemiology who risked their lives to find the source of deadly diseases--now revised to include updated information and a new chapter on Covid-19. More people have died in disease epidemics than in wars or other disasters, but the process of identifying these diseases and determining how they spread is often a terrifying gamble. Epidemiologists have been ignored, mocked, or silenced all while trying to protect the population and identify "patient zero"--the first person to have contracted the disease, and a key piece in solving the epidemic puzzle. Patient Zero tracks the gripping tales of eight epidemics and pandemics--how they started, how they spread, and the fight to stop them. This revised edition combines a brand-new design with updated information and features diseases such as Spanish Influenza, Ebola, and AIDS, as well as a new chapter on Covid-19.
