故事從 1914 年揭開序幕，距離達爾文的小獵犬號遠航，轉眼已經八十年過去。然而在《利維坦》的世界裡，他不只是發表了《物種原始》、奠定現代生物學的基礎，更發現了「生命線」（life thread, 也就是 DNA），永遠改變了世界。如今英法兩國的自然學者已經完全掌握了「合成物種」的奧秘，開啟了一個輝煌的生物科技時代。工業革命的燃煤黑煙不再，取而代之的各式各樣的合成獸，或行走於倫敦街頭、或遨翔於首都上空。
在這個被稱為「達爾文主義者」（Darwinists）的世界裡，由猛馬象改造成的長途載具取代了火車，力大無窮的狼虎合成獸成了主要的拉車馱獸，巨型飛空艇乃是帶有鯨魚基因的完整的生態系，藉由棲息其間的蜜蜂和鳥類帶回的食物排放氫氣，因而能騰空飛行。為了防止巨鯨體內的氫氣外洩，引起爆炸，自然學者又造出六隻腳的嗅氫犬（hydrogen sniffer）。空戰的主力包括吞食鐵釘而後排泄射出的飛鏢蝙蝠，以及能灑下劇毒網的戰鷹。除此之外，還有能夠「錄製」人類聲音的傳話蜥蜴（message lizard）。
與英法敵對的勢力，則是由德意志帝國和奧匈帝國組成的「叮噹同盟」（Clankers），他們信仰天主教，把達爾文主義者的生物科技視為褻瀆上帝之舉。他們相信機械的力量，製造出陸行戰艦、高速機動偵察車、搭載重機槍和主砲的人形「暴風行者」（Stormwalker）戰具。Clank 原意為金屬碰撞的叮噹聲，後為達爾文主義者便稱他們為「叮噹人」（Clanckers）。《利維坦》的兩位主角恰好來自敵對陣營，被捲入一場即將延燒全球的超級大戰。
男主角亞歷山大（Aleksandar）是奧地利斐迪南大公的獨子，但因為母親沒有皇族血統，他不能繼承父親的爵位或領土。當被大公夫婦在塞拉耶佛遇刺身亡後，亞歷立刻被帶上一具「暴風行者」，連夜逃離奧地利。表面上這是一樁綁架行動，實際上卻是大公的先見之明，他知道自己的和平主張終將引來殺機，為了保護兒子免受政敵迫害，便託付摯友瓦格伯爵（Count Volger）帶亞歷逃走。
斐迪南夫婦的暗殺事件，使得原本便一觸即發的歐洲局勢，終於全面爆發衝突。奧匈帝國立刻向塞爾維亞宣戰，而俄國為了履行盟約，立即向奧地利宣戰，接著德國向俄國宣戰，法國向德國宣戰，戰爭有如骨牌效應，在全歐蔓延開來。亞歷在瓦格伯爵和機械長柯羅普（Klopp）的引導下，一邊學習駕駛機器人，一邊躲避來自德奧兩國的追兵，前往目的地：中立國瑞士。
在遙遠的英國，女主角戴琳‧夏普（Deryn Sharp）來到首都倫敦，準備女扮男裝用「戴倫」的身份加入皇家空軍，如此才能和已經入伍的哥哥在一起。她來自蘇格蘭，從小嚮往飛行，並從父親那邊學到駕馭合成獸升空的秘訣。誰知她才第一天參加新兵選拔，就因為自告奮勇乘「赫胥黎」（Huxley，一種水母改造的合成獸，能夠產生氫氣升空，類似熱氣球）升空試膽，被暴風吹離市區，一路飄流，最後被巨型飛空艇「利維坦號」搭救，成了船上一員。
眼看英國參戰在即，「利維坦號」奉命返回倫敦，搭載一位科學家和外交官，緊急前往君士坦丁堡，執行秘密外交任務。飛船在倫敦動物園降落，戴琳驚訝地發現科學家竟是個女博士，而且還是達爾文的孫女！這位諾拉博士莫測高深，隨身的「寵物」是一隻長得很奇怪的袋狼（thycaline, 又稱「塔斯馬尼亞虎」，現已絕種），除了大批行李，她還帶了一個超重的保溫箱！
朝土耳其飛去的途中，「利維坦號」遭到德國空軍襲擊，迫降阿爾卑斯山上。本來這個生態系只要有花草植物就能自給自足，修補損傷重新出發，偏偏他們落在海拔數千公尺、花草不生的雪地裡，孤立無援。誰知失事地點正好在亞歷的藏身處附近：斐迪南大公十五年前便相中這裡的一座荒廢城堡，將內部整修後準備了超過十年份的糧食物資，為的就是要讓兒子在此躲避戰亂。
亞歷不顧瓦格伯爵的勸阻，執意向「利維坦號」伸出援手，雙方歷經猜疑、誤解到抱持戒心的互助，這時德意志大軍開到，包括最新式的八足陸上戰艦，以及會發射燃燐照明彈，足以瞬間引爆氫氣的偵察車。「利維坦號」能否擊退敵人、逃出生天？亞歷的皇儲身份和戴琳的真實性別會不會被揭穿？諾拉博士的秘密任務究竟又是什麼？

Alek and Deryn are on the last leg of their round-the-world quest to end World War I, reclaim Alek's throne as prince of Austria, and finally fall in love. The first two objectives are complicated by the fact that their ship, the Leviathan, continues to detour farther away from the heart of the war (and crown). And the love thing would be a lot easier if Alek knew Deryn was a girl. (She has to pose as a boy in order to serve in the British Air Service.) And if they weren't technically enemies. The tension thickens as the Leviathan steams toward New York City with a homicidal lunatic on board: secrets suddenly unravel, characters reappear, and nothing is at it seems in this thunderous conclusion to Scott Westerfeld's brilliant trilogy.

The behemoth is the fiercest creature in the British navy. It can swallow enemy battleships with one bite. The Darwinists will need it, now that they are at war with the Clanker powers. Deryn is a girl posing as a boy in the British Air Service, and Alek is the heir to an empire posing as a commoner. Finally together aboard the airship Leviathan , they hope to bring the war to a halt. But when disaster strikes the Leviathan 's peacekeeping mission, they find themselves alone and hunted in enemy territory. Alek and Deryn will need great skill, new allies, and brave hearts to face what's ahead.

Now in paperback, the New York Times bestselling launch of Westerfeld's masterful series that SLJ reviewd as "sure to become a classic."

Nobody's ever really explained the Spill. Was it an angelic visitation? A nanotech accident? A porthole opening from another world? Whatever it was, no one's allowed in the Spill Zone these days except government scientists and hazmat teams. But a few intrepid explorers know how to sneak through the patrols and steer clear of the dangers inside the Zone. Addison Merrick is one such explorer, dedicated to finding out what happened that night and to unraveling the events that took her parents and left her little sister mute and disconnected from the world.

Strange things happen at midnight in the town of Bixby, Oklahoma. Time freezes. Nobody moves except dark creatures that haunt the shadows and the few people who are free to move at midnight, Midnighters. Their different powers strongest at midnight are: Seer, Mindcaster, Acrobat, Polymath. All changes when Jessica Day comes to Bixby High with a hidden power.
