Sanctuary Fighting back the darkness with style.

Small Favor,  book 10 in Jim Butcher's Dresden Files series, is set for release on April Fool's Day, 2008. 

 From Jim-Butcher.com:

Jim says, "Small Favor. Because, y'know, Harry still owes two."

No one's tried to kill Harry Dresden for almost an entire year, and his
life finally seems to be calming down. For once, the future looks
fairly bright. But the past casts one hell of a long shadow.

An old bargain has placed Harry in debt to Mab, monarch of the Winter
Court of the Sidhe, the Queen of Air and Darkness-and she's calling in
her marker. It's a small favor he can't refuse...one that will trap
Harry Dresden between a nightmarish foe and an equally deadly ally, and
one that will strain his skills-and loyalties-to their very limits.

It figures. Everything was going too well to last...

To be released in hardcover from Roc publishing, April 1st, 2008.
