夜深了，安静的图书馆里突然冒出了一批夜间活动的小动物，而图书馆的小管理员也在三只猫头鹰的帮助下为每个动物找到完美的书，但随着嘈杂的松鼠乐队，狼和乌龟的加入，他们可能要忙活一晚上了……

书中的扉页插图运用深蓝色和土黄色来表现内容的静态和动态，完美的诠释了一个童话般的午夜故事。
When we are fast asleep in bed, the Midnight Library opens its doors to all the night-time animals. Inside the library the little librarian and her three assistant owls help each and every animal to find the perfect book. But with a noisy squirrel band, an upset wolf and a slow-reading tortoise to help, they could all be in for a very busy night ...A beautiful, big-hearted book about the joy of reading.
