Amy Gamet has written seven books and hit one of USA Today’s bestseller lists for her Romance Super Bundle boxed sets, which have sold nearly a quarter million copies.

And she did it all on her own as a self-published author.

Gamet joins 36 other indie authors at next weekend’s Self-Published Book Festival. The free, two-day event features workshops, panel discussions, readings, a book fair and more at the Central Library of Rochester and Monroe County, and will be bigger than its one-day predecessor held in Feburary 2014, which drew nearly 300 people.

From how to get started in the self-publishing world to book promotion, those who have chosen the independent route — in poetry, mystery, urban fiction and other genres for both children and adults — will share stories and tips on ways to become part of a trend that is revolutionizing the publishing industry.

“Self-publishing used to have this stigma and wasn’t taken seriously, but now it’s really becoming a viable way to put your book out there,” says Jennifer Blanchard of Gates, the author of five self-published books (one novel, SoundCheck, and four how-to books on writing and creativity) and a presenter at the festival. “The industry is growing and changing so much, and the library is on the cutting edge of having this information out there.”

Indie authors have given the traditional publishing world lots to talk about — and reasons to strategize — in recent years. They’ve broken onto the New York Times bestseller lists and been known to reel in six-figure advances. New York Times bestselling author Eileen Goudge, first published the traditional way, made news in 2014 when she self-published her mystery novel Bones and Roses after failing to find a publisher.

The potential profits are enticing: According to ebook distribution platform Smashwords, self-published ebook authors typically earn royalties between 60 percent and 80 percent of their book’s list price, compared with between 12 percent and 17 percent for traditionally published ebook authors.

For authors looking for advice and networking opportunities, new to this year’s festival is a small trade show featuring local consultants and collaborators, including editors. Peggy DeKay, a Kentucky-based book coach and author of Self-Publishing for Virgins: The First-Time Author’s Guide to Self Publishing Simply and Profitably, is the keynote speaker.

Retired homebuilder Rick Garvia is one of four authors in a panel discussion on the self-publishing process. He’s the author of The Road Gets Longer If I Stop, a collection of 41 essays about “the frustrations of modern life for people of my age bracket.”

“It’s not David Barry toilet humor and it’s not David Sedaris’ ironic New Yorker humor,” he says. “It’s somewhere in between.”

Garvia also plans to learn a few things himself at the festival, such as how to better market his second book of essays, which he’s currently writing. “I just assumed that the world would love it, and Ellen would be calling me, and I’d be on her show,” he admits. “But I’m still trying to unload inventory.”

Despite the extra work that comes with independently publishing your own book, self-publishing is “a really a great avenue to your work out there,” says Gamet, whose “Secrets from a Bestselling Self-Published Author” workshop will focus on how authors can make their books more conspicuous at retailers. “A lot of people dream of writing a book. This way you don’t have to go through all the rejections.”
