(Reuters) - J.K. Rowling, whose "Harry Potter" fantasy book series became a global publishing phenomenon, is writing her first novel for adults but the title and plot are still a closely-guarded secret.

The British writer, 46, whose teenage boy wizard tales became international best-sellers and inspired a series of hit films, said on Thursday that her new novel would be "very different" to the "Harry Potter" books that made her a household name and turned her into a billionaire.

"Although I've enjoyed writing it every bit as much, my next book will be very different to the Harry Potter series," Rowling said in a statement.

WTNH on YouTube: On Thursday, Borders will ask a judge to begin liquidation of the company.

Borders Group Inc, the second-largest U.S. bookstore chain, said it has canceled an upcoming bankruptcy auction and will close its doors for good.

The company said in a statement Monday it was unable to find a buyer willing to keep it in operation and will sell itself to a group of liquidators led by Hilco Merchant Resources.

Borders' roughly 400 remaining stores will close, and nearly 11,000 jobs will be lost, according to the company.

"We are saddened by this development," Borders President Mike Edwards said in the statement. "We were all working hard toward a different outcome, but the headwinds we have been facing for quite some time ... have brought us to where we are now."

I figured that you would write about President Obama, along with the rest of the International Energy Agency, releasing oil from their reserves. If I had written a Karnak predicts post, both of those topics would have been in it, but I didn't. However, I did write about that topic and predicted that you'd have something snarky to say about it, and I was right. Unfortunately, I buried the lede and made the title about falling gas prices in Detroit, when the story really was about Obama trying to stimulate the economy to help his re-election while at the same time kicking the oil companies and commodities speculators while the price goes down. So far, it's working.

If that price holds, AAA Michigan and the Detroit Free Press will have another price drop to report next week.

I'm sure they will, as the price of oil dropped 4% yesterday.

SYDNEY (Reuters) - The dollar rebounded from three-year lows and U.S. crude slid more than 1 percent on Monday after news al Qaeda leader Osama bin Laden was killed in a firefight with U.S. forces reduced the perception of security risks facing the United States.

"By lowering national security risks overall, this is likely to bolster equity markets and lower U.S. Treasury prices in a reverse flight to quality movement," said Mohamed El-Erian, Chief Executive Officer and Co-Chief Investment Officer at PIMCO, which oversees $1.2 trillion in assets.

"Oil markets are likely to be the most volatile given their higher sensitivity to the tug of war between lower risk overall and the possibility of isolated disturbances in some parts of the Middle East and central Asia," he said.

U.S. crude fell more than 1 percent to a session low of $112.21, retreating from a 31-month peak of $114.18 set on Friday.

The dollar index .DXY, which tracks its performance against a basket of major currencies, jumped from a three-year low of 72.813 to 73.227.

Still, once the dust settles, analysts expect the recent trends including a weak U.S. dollar and higher commodity prices to resume, especially given that the U.S. Federal Reserve in no hurry to tighten its ultra-loose monetary policy.

"The economic data in the U.S. is still going to be on the soft side and the market is going to keep a lid on yields and that is going to help push down the dollar," said Joseph Capurso, strategist at Commonwealth Bank.

Some were also skeptical of whether bin Laden death would reduce the security risks facing the United States.

"It doesn't change much about the energy situation and doesn't change much about the ongoing battle with radical Islamists," said Chip Hanlon, president of Delta Global Advisors in California.

"It's sort of like the news when we heard Saddam (Hussein) was caught, in the end it didn't change much fundamentally and I don't think this will either."
