This week's new books include Michael Phelps' No Limits, which describes his record gold medal sweep at the Beijing Olympics.

No Limits: The Will to Succeed (Free Press, $26). Phelps reveals the secrets to his remarkable success, from his training regimen to his mental preparation and, finally, to his performance in the pool. If you want a signed copy, Phelps will hold a book signing Saturday at the Inner Harbor Barnes & Noble, starting at 12:30 p.m.

The Treasure by Iris Johansen (Bantam, $25) Set largely in 12th-century Europe, this intricately plotted historical romance, the sequel to Lion’s Bride, is replete with majestic castles, ruthless assassins and gentlemen rogues. Two lovers are unwilling participants in a deadly struggle for control of an artifact that could contain the secret to immortality.

Victor Fleming: An American Movie Master by Sun movie critic Michael Sragow. Fleming, though an obscure figure today, was a film-making giant in early Hollywood. He helped mold stars such as Clark Gable, Gary Cooper and Jean Harlow. And he salvaged both The Wizard of Oz and Gone With the Wind, which had run into trouble with their original directors.
