Y'all, I don't think I can express how friggin excited I am by this news. Now, you all know I like me some Bear. This is understood. But, I love me some Promethean Age. One Eyed Jack and the Suicide King is the fifth volume in Bear's Promethean Age series, which we have neither seen nor heard a peep of since 2008 as Roc, the previous publisher, declined to buy any more of these damned wonderful fantastic novels.
From Bear's livejournal, she writes
I should mention that this book takes place between Blood & Iron and Whiskey & Water, except the bits that take place long before either, and it's on the opposite coast. So it totally functions as a stand-alone novel.
Waaaay back in 2007, Subterranean Press published an excerpt. Go take a gander.
Can't. Friggin. Wait.
