It feels like we haven't heard from Samantha Markle, Duchess Meghan Markle's rogue and bitter half-sister, for at least a hot minute.
In The Shadows Of The Duchess, which was previously titled The Diary of Princess Pushy's Sister, is a memoir that will apparently "hold nothing back" and will expose all of Meghan's alleged "lies".
In an interview with the Daily Star Online Samantha claimed that the world "does not know the total truth" about the newest royal.
"From lullabies to lies... it's all they're in my book," she said.
Since her sister's marriage to Prince Harry in May this year, it appears that Samantha has been the victim of some serious "cyber bullying."
"On top of it I am dealing with cyber stalking and cyber bullying with little Twitter trolls… they're kind of nasty sending out banners and propaganda about me that's disparaging and not true," she said.
"They have been reported to the FBI and they were calling in death threats to radio stations (too), so the FBI and police have their phone numbers and their addresses."
While Meg's half-sister hasn't revealed exactly what's in the book about her famous sibling, it will showcase a massive family fight that involves Meghan's nephew Tyler Dooley.
Tyler, who is the son of Thomas Markle Jr - Meghan's half-brother, is also set to star in an explosive new MTV reality show called The Royal World.
According to MTV, the show is all about "a squad of sophisticated young royals and aristocrats who stay in a mansion in the British countryside."
It promises to deliver "outrageous behaviour as these darlings drink and host house parties that will make us well jealous of their unbelievable life."
So in a nutshell, it rounds up long lost relatives with tenuous links to royalty, puts them in a mansion in Surrey for two weeks, gets them drunk and let's the dirty laundry flow.

As Meghan's life as a royal continues, her family are continuously daring to bring her down, however, it is of course Samantha that is the unwanted gift that keeps on giving.
During the Royal tour Down Under, sister Sammy was at it again.
When the Duchess of Sussex made her first speech as an official member of the royal family, she drew on her own experiences as a university student and confessed she had relied on "scholarships and financial aid programmes," to earn her degree.
Of course, sister Sammy had something to say about it and was quick to take to Twitter and say that their father, Thomas Markle financed her tertiary education.
"Dad paid her college tuition! She forgot the most important part of her speech and there are receipts to prove it. I love my sister but this is ridiculous. You can't lie like this, Meg! Delusionally absurd," she penned on social media.
In his book Meghan: A Hollywood Princess, royal biographer Andrew Morton says that Meghan's father won the California State Lottery in 1990, "scooping $US750,000 with five numbers, which included Meghan's birth date," and used the money to fund her $16,000-a-year school tuition at Immaculate Heart Catholic School, one of LA's finest schools, as well as her university education.
Speaking to The Mail on Sunday, Thomas Markle has revealed, "When Meghan was 11, she moved back in with me up until she was 17 and went to college."
"I was having my good years then, making good money, and could afford to give her the best, with a good school, good education, good home."
"She became the woman that she is today thanks to everything I did for her."
Back in early October, it seemed Samantha was ready to make amends with her little sister.
On Channel 5's Jeremy Vine, Samantha said: "I wish things could be different."
The pair have apparently not seen each other for more than a decade and she hoped they could "move forward with peaceful resolve".
To make peace, the author even took responsibility for the staged paparazzi photos involving their father Thomas, which catapulted him into international infamy.
"I have to say I am entirely the culprit," Samantha explained during an interview on British talk show Loose Women.
"As we know the media can take very unflattering photographs of people on their casual days and blow it way out of proportion. I said, you know, the world has no idea you're getting in shape, doing healthy things. They don't photograph you buying vegetables and PH water. They photograph you as unflattering ways as they can," Samantha, who was not invited to the wedding, claimed.
"So I said, really you need to show the world that you're getting in shape and doing great healthy things. "
"So I suggested it. There's a lot of scrutiny that it was money motivated, it was not. It was my suggestion that to benefit him and to benefit the royal family that everyone looked good and they depict you as you are – in shape and doing healthy things."
As the Markle debacle continues, we can only imagine that Samantha will come out with more "information", continuing to ride on the coattails of her extremely famous sister.
