Hunter Biden is publishing a book about his struggles with addiction

• Hunter Biden, President Joe Biden's oldest surviving child, is coming out with a book.
• His memoir "Beautiful Things" is set for an April 6 release.
• The book has already earned plaudits from authors such as Stephen King.

Hunter Biden has written a book, "Beautiful Things: A Memoir," that's set for an April 6 release.

The rights to the Biden book were acquired by Gallery Books, a division of Simon & Schuster, in the fall of 2019, according to the Associated Press.

As the youngest surviving child of President Joe Biden, Hunter became a focal point in conservative media during the 2020 campaign.

His business dealings in Ukraine were the subject of former President Donald Trump's infamous phone call with the Ukrainian president, culminating in his first impeachment.

Hunter's book addresses his substance use disorder, which has been the other major component of his press coverage and something that President Biden addressed as a candidate.

"My son, like a lot of people, like a lot of people you know at home, had a drug problem," Biden said to Trump during their first debate. "He's overtaken it. He's fixed it. He's worked on it, and I'm proud of him. I'm proud of my son."

The way Hunter approached writing about such an internal struggle earned praise from authors who got an advance copy of the book, including Stephen King.

"In his harrowing and compulsively readable memoir, Hunter Biden proves again that anybody - even the son of a United States President - can take a ride on the pink horse down nightmare alley," King wrote in a blurb for the book.

"Biden remembers it all and tells it all with a bravery that is both heartbreaking and quite gorgeous," King continued. "He starts with a question: Where's Hunter? The answer is he's in this book, the good, the bad, and the beautiful."
