Former U.S. Ambassador to Ukraine Marie Yovanovitch, a key figure in the impeachment of President Trump, landed a book deal about her time as a career diplomat.

Houghton Mifflin Harcourt told the Associated Press that it would publish Yovanovitch’s memoir, which is expected to be released in spring 2021. Two people familiar with the deal said it was worth seven figures.

The book will reflect on her career from Mogadishu, Somalia, to Kyiv and “finally back to Washington, D.C. — where, to her dismay, she found a political system beset by many of the same challenges she had spent her career combating overseas,” according to the publisher.

“Yovanovitch’s book will deliver pointed reflections on the issues confronting America today, and thoughts on how we can shore up our democracy,” Houghton Mifflin Harcourt said in an announcement.

Yovanovitch was ousted from her position in Kyiv in early 2019 on Trump’s orders. She testified during the impeachment investigation that her reputation was smeared by Trump’s personal lawyer, Rudy Giuliani, who spread disinformation that she had been blocking corruption investigations into 2020 presidential candidate Joe Biden and his son Hunter, who was on the board of a Ukrainian gas company while his father was vice president.

Trump recalled her from Kyiv after Giuliani and a Ukrainian prosecutor accused her of being a political enemy of the White House.

The president also criticized her in a phone call with Ukrainian President Volodymyr Zelensky when he urged the new Ukrainian leader to work with Giuliani, who sought to find dirt on the Bidens.

Yovanovitch was appointed ambassador to Ukraine in 2016 by President Barack Obama. Before her retirement earlier this month, she had been a foreign officer for 33 years, serving in four Republican and two Democratic presidential administrations. She was also the ambassador to Kyrgyzstan and Armenia.
