HOLLYWOOD, Calif. – Sex educator and author Amberly Rothfield’s new book 90 Days and Paid, now available for preorders, has quickly become the #1 new release in Amazon’s small business category “due to the incredible demand”, Rothfield announced over the weekend.

Rothfield’s latest release is “designed as a workbook meant to be completed over a 90-day period,” Rothfield said in a statement released Saturday. “It focuses on developing lasting skills and a solid schedule rather than specific tips and tricks and features quotes from models across the industry.”

The book will be released on July 31 and can be preordered on Amazon for $0.99. It is currently only available for Kindle, though Rothfield said physical and audiobook versions are planned, as well.

“I’m honestly having a hard time believing it,” Rothfield said of the book reaching the top spot in the small business category. “I never expected that this book would be so popular or become a #1 anything, especially not before it has even been officially released. This is truly a testament to models desire to really put in the work.”

In addition to her books and speaking engagements, Rothfield also offers one-on-one consultations with models who are interested in growing their brand. For more information and rates, check out Rothfield’s page on Calendly.com.
