如果世界被鎖上
就讓自己成為鑰匙

第一本禁書是誰決定的？
是誰關上知識的大門？
又是誰，帶圖書館走入黑暗？

一封寫給言論自由與知識的情書，將對書的愛情以及自由閱讀的美好，以動作冒險的形式來呈現。――Goodread讀者Justine

傑斯帶著少得可憐的革命伙伴闖入羅馬賽拉潘神殿，只為救出摯友湯瑪士――他發明足以妨害圖書館政權的機械，因此被關入牢中。眾人為躲避追殺，一路從亞歷山大逃到羅馬、再從羅馬躲往倫敦，最後遭傑斯的父親背叛，直接被送入縱火手的大本營：美國費城。

然而，身為圖書館員，這是他們絕不能踏入的禁地――此處居民將圖書館當作敵人，欲殺之而後快；他們不過是從獅子的爪下，轉至老虎的口中。為了活命，傑斯與湯瑪士與縱火手的首領交換條件，幫他打造圖書館最畏懼的機器――印壓機。但等在城外的圖書館軍隊卻失去了耐心，下達了泯滅人性的命令――殲滅費城、一個人都不留！

儘管這座銅牆鐵壁撐了一百年，但當希臘火藥如流星雨般墜入城中，一切都將熊熊燃燒――書本、印壓機、縱火手、無辜百姓――還有傑斯和他的朋友……


Hoarding all the knowledge of the world, the Great Library jealously guards its secrets. But now a group of rebels poses a dangerous threat to its tyranny....

Jess Brightwell and his band of exiles have fled London, only to find themselves imprisoned in Philadelphia, a city led by those who would rather burn books than submit.

But Jess and his friends have a bargaining chip: the knowledge to build a machine that will break the Library's rule.

Their time is running out. To survive, they'll have to choose to live or die as one, to take the fight to their enemies--and to save the very soul of the Great Library....
