Fifty Shades of Grey

Started life as a Twilight fanfic called "Master of the Universe". Basically, same characters, but less vampire, more sex. Then, the character names were changed from Edward Cullen and Bella Swan to Christian Grey and Anastasia Steele, and now it is not a fanfic but legit fic for sale.

"...reimagine [s the Bella and Edward love affair set in contemporary Seattle, Washington with Bella as the young college graduate virgin and Edward as the masterful billionaire with secret sexual predilections."]

Tropes used:

 * Abuse Is Okay When It Is Female On Male: Subverted.
 * All Girls Want Bad Boys: Literally. Almost all women in the series are attracted to Christian. Those who aren't are related or lesbians.
 * All Women are Doms, All Men are Subs: Averted, for once.
 * Amicable Exes
 * Analogy Backfire: Ana compares herself to Tess Durbeyfield and Icarus. Both times ignoring the part where those two characters die.
 * Anticlimax
 * Attempted Rape
 * Blondes Are Unpleasant
 * Cool Car
 * Dark and Troubled Past: Christian Grey. Had an abusive childhood. Refers to his mother as "Crack whore".
 * Did Not Do the Research: BDSM and psychology are the most glaringly obvious examples, but there are other errors too.
 * Disappeared Dad: Both Christian and Ana.
 * Disproportionate Retribution
 * Double Entendre
 * Double Standard
 * Drama Queen: Anastasia.
 * Expy: A lot of characters are similar to their original Twilight templates, with some characteristic of movie actors mixed in: Ana is a clumsy virgin who bites her lip a lot and has an absent-minded mother. Christian is an orphan adopted into a rich family, one of his adoptive parents is a doctor, he plays piano and has a brother and a sister . Etc ad nauseam.
 * Food Porn
 * Freudian Excuse/Single-Issue Psychology: Christian
 * I Can Change My Beloved: Eventually switches to nauseating Love Redeems, without any real reason.
 * Love Martyr: Anastasia.
 * The Ingenue: Anastasia Steele. Twenty-one, naive, and so virginal she never even masturbated before meeting Christian Grey.
 * Mills and Boon Prose
 * Meaningful Name: Jack Hyde.
 * Mommy Issues: Christian.
 * Names to Run Away From Really Fast: Jack Hyde.
 * Parental Neglect: Christian. Your Mileage May Vary on whether it's two times around.
 * Pimped-Out Car: And a Pimped Out Helicopter, too.
 * Porn Stash: Homemade, at that.
 * Purple Prose: You beguile me, Christian. Completely overwhelm me. I feel like Icarus flying too close to the sun.
 * Self-Plagiarism: First book matches the first third of the fanfic 89%.
 * Therapy Is for the Weak: Christian seems to think so. So does his adoptive family, probably. Seeing as they adopted a deeply traumatised child and never bothered to seek professional help. There is a psychiatrist, but he is only there for exposition.
 * What Do You Mean It's Not Heinous?
 * Yandere: Leila, Christian's ex-sub.
 * You Keep Using That Word: If you drank every time the inner goddess is mentioned, you'd be dead before the first third of the book.
