Strap on your aviator goggles — the next book in Scott Westerfeld's "dieselpunk" World War I saga is coming!S

Now that Scott Westerfeld's Leviathan has won a Locus Award, we're even more excited to read the next chapter in the alternate-universe World War I saga. Here's your exclusive first look at the cover of book two, Behemoth. Spoilers below.

What's this book about? All we know is that Westerfeld's saga ventures into the Ottoman Empire, which has walkers shaped like animals. We're hoping to be able to share some exclusive Keith Thompson art of "Clanker Istanbul" soon. And the third book in the series promises to go even further afield. Behemoth comes out October 5.
