"The Hangman's Daughter" series, published by Amazon Publishing sold its first million copies, the company revealed.

Oliver Pötzsch became the first Amazon Publishing author to sell one million copies when when his "The Hangman's Daughter" series consisting of novels "The Hangman's Daughter" (2010), "The Dark Monk" (2012), and "The Beggar King" (2013) reached its first million sales mark in combined print, audio, and Kindle English language editions worldwide.

"We congratulate Oliver on this great achievement," said Jeff Belle, Vice President, Amazon Publishing in a press release. "So few books from around the world are translated into English. Our goal with AmazonCrossing is to bring more of the world's great authors to a global audience. Oliver's novels deserve the broadest possible readership, and we're proud to be able to bring them to the attention of the English-speaking world."

The series was first published by Ullstein in Pötzsch's native German and was later translated into English and published in digital editions by AmazonCrossing, Amazon Publishing's imprint focused on acquiring exceptional works of world literature for translation. The first book of the series was noted to be the #1 bestselling Kindle book.

"If somebody had told me a few years ago that I would sell a million copies of a story about a Bavarian hangman, I would have called him completely nuts!" said Pötzsch. "I am thankful for the great cooperation and creative energy of the great colleagues at AmazonCrossing for helping to make this possible."

The fourth book in the series, "The Poisoned Pilgrim," will release on July 16th.
