"I said I was going to do it, and here it is!" Banks, 36, writes in a note to fans posted Tuesday on Tyra.com. "It's for all the girls and guys who want a lot more FANTASY in their lives … and some fierceness and magic, romance and mystery, crazy and wild adventures, and yeah, some danger too.
"It's my novel called Modelland (pronounced "Model Land") that takes you to a fantastical place you've never seen, or heard about, or read about before ... Where dreams come true and life can change in the blink of a smoky eye."
The novel is part of a three-book deal with Random House. No details of the plot or publishing date were available, but Banks says the novel has floated around in her imagination for a long time.
"Modelland has always been a part of my mind and my heart," she says. "I'm excited that you'll be able to read about this magical world that's been living in my dreams for so many years."
While this is Banks's first foray into fiction, she did publish a book in 1998 titled Tyra's Beauty, Inside and Out, offering tips for women to make the most of their natural beauty.
