"Fifty Shades of Grey" fans are looking for the next erotic book to sweep them off their feet and keep their summer sizzling all the way into winter.

"South of Bixby Bridge" might just be that book. Reviews called it the next "Fifty Shades."

Written by Ryan Winfield, the novel was first published in 2011 by Birch Paper Press. It recently was released as a Kindle Edition on Aug. 15.

The book is described:

About to turn 30 and being discharged from drug rehab, Trevor Roberts is sure he's hit bottom with nowhere to go but up. He soon learns that sometimes the "bottom" is just the beginning. With more twists than California's Highway 1, the intimate narrative follows a young man on a wild month-long ride to the dizzying, drunken heights of Napa Valley excess where he falls fast for his new boss's intoxicating wife and becomes entangled in a strange threesome affair. But things soon begin to unravel as Trevor is drawn into a secret world of sex and scandal, only to have his lust for success drag him down again through a phantasmagoria of hedonistic hell.

"Shocking and unapologetic," South of Bixby Bridge barrels along with the "frenetic pace of a Hollywood blockbuster," delivering "poetic prose loaded with images." With gripping drama, witty dialogue, and sexy, jaw-dropping glimpses into the nouveau-riche underworld of California's wealthy elite, you won't be able to put this riveting new novel down. Buckle up and enjoy the read!

"South of Bixby Bridge" is on the Kindle Top 100 Paid List Bestseller and is#1 Amazon Kindle Bestseller in U.S. Literature & Fiction.

Stewart Stern, Emmy winning screenwriter of "Sybil" and "Rebel Without a Cause," gave a review: Ryan Winfield has been preparing himself all his life to produce the wonder to which this first novel ascends. It is a glorious debut for an artist who has never stopped inhaling all he sees or feels empathically for others during his own long climb out of the dark... I commend - without reservation and to every one who reads or wants to write - this moving, funny, sexy, infinitely human book.

Here are what some readers had to say:

• Mr. Winfield, you've got my attention. SOUTH OF BIXBY BRIDGE is a stand out. Addiction, abuse, heartbreak, corruption~~the story of 'Trevor' pulled me in and will stay with me forever. This is a book that you will never, ever, forget. I'm certain that we will be seeing much more from Mr. Winfield.
• Oh. My Gods! This is the best book I've read in a long time. I'm going to have a hard time letting go of Trevor. He touched me that deeply and I just want to hug him and tell him it'll be alright.
• I love reading debut novels and this did not disappoint. The story of Trevor grabs you from the very first page and does not let you go. I finished in one sitting and will be thinking about this book for some time. Ryan Winfield is a very gifted writer. Looking forward to more of his work.
• This book kept me turning pages and looking for moments to squeeze in just a few more. I enjoyed it thoroughly, ok maybe some of sex could have been a little less graphic, but having said that; I will look forward to more from this author.
• Fast, suspenseful, passionate, gut wrenching, and sometimes shocking. It tells the story of a young man's journey through the valley from the depths of hell to the pinnacle of peace.
