Empire of Ivory (Book Four, Temeraire Series)

Plague has spread across the British Isles. Dragons everywhere are falling sick and dying, that is, except for Temeraire. Realizing the importance of his immunity, the British government chooses to send Temeraire, and his captain William Laurence, to try to find a cure. Sent to the jungles of Africa by way of ship, Laurence and Temeriare must cut their way across the massive continent before time runs out. Meanwhile, Napoleon's power is growing and is taking advantage of the Areal Corps' weakness by planning a full-fledged invasion of Britain. The clock is ticking and Laurence must find the cure before it is too late, for the dragons and for Britain. When Napoleon's dragons fall ill too, Laurence must make a decision that will change his life forever.

Empire of Ivory is full of suspense, action, plot twists and, most importantly, new dragons. This book was so riveting that it was almost impossible to tear myself away until it was finished. Like the other books in the series, the language in which Novik writes compliments the novel and the era,  making this book and this series a thrill ride.
