The high-stress world of hedge funds is certainly daunting for all of those who work in it. Carrie Sun — the former personal assistant to a billionaire hedge fund manager — has authored a new book called Private Equity documenting her years as an assistant and the trauma-inducing experiences that it brought.

Sun joins Yahoo Finance to discuss her new book and the revelations of working for hedge funds that it showcases.

Sun explains some of her feelings towards her ex-boss and the pressures of the job: "I wanted to communicate through the book that we... are all kind of on this treadmill of burnout and extreme, intense work altogether because I do still feel kindly toward him, and I think ultimately... he valued me a lot. " She continues on to say: "At the same time when I was driven to the ground with my burnout and I tried to speak up and ask him for help just in terms of possibly hiring another person to assist me... and he just wasn't able to get there for whatever reason."

- Time now to get an inside look at the world of high finance. Our next guest was once an assistant to a billionaire, hedge fund manager, and has now written a new book private equity that delves into the world of the 1% and the expectations that come with working in that world.

Carrie Sun joins us now. Carrie, welcome to the show. And listen, congrats on the new on the new book.

Maybe to start, Carrie, you can just walk us through how you came to work for this hedge fund billionaire, Carrie. And what kind of work were you doing? What exactly was the role?

CARRIE SUN: The role was the right-hand person to this hedge fund billionaire. And I was really in charge of managing his life. I provided him with both administrative support, as well as research and operational. And I really just gave him hopefully extra time in his life to be able to do some higher return on time activities.

- And it's so interesting to me, Carrie. The way that you put that, that hopefully you gave him some extra. I mean, clearly, you still feel kindly towards this person it seems.

You wanted to do a good job. At the same time that it sounds like the job kind of ground you into the ground, right? It was exhausting. So how did you come out of that experience and say, OK, this is a book I want to write about this? And what did you want to communicate through the book?

CARRIE SUN: I wanted to communicate through the book that by we, I really actually do mean this grand where I'm talking about myself, but certainly my boss in the book, are all on this treadmill of burnout, and extreme, intense work altogether. Because I do still feel kindly toward him.

And I think, ultimately, you know, I think he valued me a lot. I did provide him I think with a lot of value. And he rewarded me by giving me raises, bonuses, and a lot of gifts.

And in addition to that, he said some very words of praise toward me. And I think he really believed in my abilities. But at the same time, when I was driven to the ground with my burnout, and I tried to speak up, and ask him for help, just in terms of possibly hiring another person to assist me, there was just not enough hours in the day to do the volume work that was required.

And I asked him for help. And he just wasn't able to get there for whatever reason. And so in my book, I'm trying to show how we tell ourselves these stories about who we are and what we believe about work.

And I think the story that he might have told himself was that perhaps like he was a kind giving boss. And I think he thought that he was pretty chill and easy going and not that intense or required so much, and that he thought that my job was perhaps not so difficult. And when I told him about my burnout, I'm not sure that he actually really believed me.

- And Carrie, I'm also interested. You changed the name of the people and the firm that you work with. Why did you decide to do that, Carrie?

CARRIE SUN: I decided to do that because I really wanted to focus the story on my own story. There are so many wonderful books written from the perspective of bosses. And many of whom are billionaires and owners of these fantastic firms.

But I really wanted to read a story set in that world, but from the perspective of an average worker. And I wanted to provide that story. I wanted to write what I wanted to read.

And because I think there's room for voices in that world beyond those who call the shots.
