時間：二次大戰期間。地點：波蘭。8歲小女孩Anna，因為爸爸的關係，會很多國語言。某天，爸爸突然離去不復返，站在街道外的Anna苦等不到爸爸，卻遇到一位懂鳥語的燕子人（Swallow Man）。Anna亦步亦趨跟著燕子人，好得到照應。有語言天分的Anna學習鳥語快速，兩人便發展出鳥語交談模式。燕子人教Anna如何躲炸彈、喬裝…等生存技倆，保持低調，避免惹禍上身。燕子人不太表達情感，但Anna知道自己無時不被豐厚的羽翼庇祐著 （請讀者拉高角度，看封面女孩的上方）。作者刻意不透露太多燕子人的過去，只偶爾留有線索：他也曾有個女兒…
Anna and the Swallow Man is a stunning, literary, and wholly original debut novel that tells a new WW2 story.
Kraków, 1939, is no place to grow up. There are a million marching soldiers and a thousand barking dogs. And Anna Lania is just seven years old when the Germans take her father and suddenly, she’s alone.
Then she meets the Swallow Man. He is a mystery, strange and tall. And like Anna's missing father, he has a gift for languages: Polish, Russian, German, Yiddish, even Bird. When he summons a bright, beautiful swallow down to his hand to stop her from crying, Anna is entranced.
Over the course of their travels together, Anna and the Swallow Man will dodge bombs, tame soldiers, and even, despite their better judgement, make a friend. But in a world gone mad, everything can prove dangerous . . .
