From the Sibert Honor-winning creator behind The Unwanted and Drowned City comes one of the darkest episodes in American history: the Spanish Influenza epidemic of 1918. This nonfiction graphic novel explores the causes, effects, and lessons learned from a major epidemic in our past, and is the perfect tool for engaging readers of all ages, especially teens and tweens learning from home. New Year's Day, 1918. America has declared war on Germany and is gathering troops to fight. But there's something coming that is deadlier than any war. When people begin to fall ill, most Americans don't suspect influenza. The flu is known to be dangerous to the very old, young, or frail. But the Spanish flu is exceptionally violent. Soon, thousands of people succumb. Then tens of thousands . . . hundreds of thousands and more. Graves can't be dug quickly enough. What made the influenza of 1918 so exceptionally deadly--and what can modern science help us understand about this tragic episode in history?

A text that has been poorly understood and unfairly denigrated over the yearsThe Liezi is a work attributed to the Daoist Lie Yukou, who, according to the traditional account, lived during the later part of the fifth and first part of the fourth centuries BCE. This places him between the first wave of philosophers of the pre-Han “Hundred Schools” (notably Lao Zi, Confucius, Mo Di, and Deng Xi) and the second wave, from mid-fourth to the end of the third centuries BCE. Thus, he may be said to have responded to the former and prefigured the latter.The Liezi we have today is the recension by the Xuanxue (Dark Learning, third to fifth centuries CE) scholar Zhang Zhan and is accompanied by Zhang’s commentary, which is a philosophical work in its own right and comparable to the commentaries of Wang Bi on the Laozi and Guo Xiang on the Zhuangzi. It is an engaging work, presenting profound philosophical ideas in a straightforward, down-to-earth, and sometimes humorous way, which makes it an ad

“In order to afford their readers optimal access to a text that has been poorly understood and unfairly denigrated over the years, in addition to their definitive English translation and their critical Chinese text, Ian Johnston and Wang Ping have provided us with the broadest interpretative context imaginable.” —ROGER T.
