It’s THE hot new book celebrity women all want to get their hands on — and it’s already been featured on  "The Today Show," FOX and CNN!

"Between a Rock and a Hot Place: Why Fifty Is Not the New Thirty" has just been penned by Hollywood screenwriter Tracey Jackson.

Published by Harper Collins, it’s a hilarious, bare-knuckled, and ultimately practical appraisal of what it REALLY means to be a 50-year-old woman today.

As Tracey, 52, tells The ENQUIRER in a website exclusive, "Fifty arrives with more baggage than Paris Hilton on a press tour!"

While "Confessions of a Shopaholic" and one of the first Hollywood/Bollywood movies "The Guru" are among her on-screen successes, Tracey credits blogging with giving her the confidence to write her first book.

Tracey takes readers through the things she learned – and didn’t learn – en route to 50.

In a mix of memoir, self-help and cultural critique, she moves from such topics as discussing physical changes ("Menopause or Menostop") to the perilous world of online dating ("Sex, Estrogen, and Not So Much Rock and Roll").

Industry publication "Booklist" commented, "Glib, gossipy, and genuinely gutsy, Jackson’s take on this middle-aged milestone will have any woman who is 50, approaching 50, or waving bye-bye in the rear-view mirror wondering, ‘Who is this woman and how did she get inside my head?’"

And praised Erica Jong, "A fiercely funny book about a most unfunny subject-aging."
