Dina (l.) and Lindsay Lohan were a sight for sore eyes in New York City on Sept. 14.

LOS ANGELES - Dina Lohan is shopping a book about her rehab recidivist daughter - but she vows it's not a damaging tell-all.

But without serving up any "juicy" details, her chances of getting a huge payday appear slim, a publishing expert told the Daily News.

"Dina has not written a book yet and has not signed with a publisher. If and when that happens, her book would certainly show the utmost compassion for her children," Dina Lohan's spokesman said in a statement.

"Right now, her focus is on the well-being of her family," publicist Steve Honig said.

The damage-control statement came after TMZ.com obtained the Long Island momager's proposal and published excerpts, which said the tome would "blow the lid" off of Lindsay Lohan's "dark secrets."

TMZ said Dina Lohan was seeking meetings with publishing types as recently as two weeks ago - around the same time her famous daughter was struggling to keep her shoplifting and double DUI probation on track.

The book's draft prologue portrays Dina as a helpless cog in the Hollywood-industrial complex, TMZ said.

"I blamed her friends, her career and her handlers for a (sic) newfound lifestyle of partying excessively. Drinking, drugging and behaving irresponsibly became Lindsay's way of daily living - and it tore me up inside," the prologue reads.

Dina says she had no choice but to s! end her Disney-star daughter off to live in Los Angeles hotels as a teenager.

"How could I deny my daughter the chance of a lifetime? How could I hold Lindsay back from her dream of becoming an actress? So, I listened to others and sent my daughter to Hollywood with a few pieces of luggage and a chaperone," Dina Lohan said in words reportedly penned by a hired ghost-writer.

She said that by the time LiLo's partying led to rehab and arrests, the actress was too old to order around anymore. And she confesses she was conflicted because she was both Lindsay's mother and manager.

According to TMZ, Dina Lohan and her rep were soliciting brainstorming meetings with publishers earlier this month, hoping to make the book a "best seller."

"It's possible it could get bought. People still care about (Lindsay Lohan), but it's tricky. She's in the tabloids all the time, and she's not such a sympathetic character," said Rachel Deahl, a senior news editor at Publishers Weekly.

"If something catastrophic happened, the book would be in demand. But it's been more of the same with her," Deahl said of the "Freaky Friday" star.

"Dina is going to have to have something juicy. If not, I don't really see the point. She's just trying to compete with the intense tabloid cycle."

Deahl doubted Dina Lohan could snag a deal north of six figures.
