When former White House photographer Pete Souza first went viral for trolling President Trump with photographs from the Obama administration on Instagram, he admitted to PEOPLE that he initially didn’t know what “throwing shade” meant. But he definitely does now.

On Wednesday, his publisher Little, Brown and Company announced the title of his new book,SHADE: A Tale of Two Presidents, which will publish on Oct. 16.

“In addition to throwing shade, this book shines a light on the presidency and on our individual roles as citizens,” said Reagan Arthur, the Senior Vice President and Publisher of Little, Brown and Company, in the statement, “reminding each of us how much our votes and voices matter.”

Souza, who shot almost two million photos while serving as Chief Official White House Photographer for President Obama, now has close to two million Instagram followers. And they love his sly, and timely, humor.

Recently, he noted that former President Obama always made a point ofgetting his wife a birthday gift, unlike President Trump.

“Singing Happy Birthday to the First Lady in 2013. He always gave her a present too,” Souza captioned a shot of the 44th president serenadingMichelle Obama.

Souza has also used his Instagram page to point out the lack of women in Trump’s administration, his rocky first 100 days in office, his eyebrow-raising “shove” of a NATO leader, and much more.

“It’s funny that people think I had some grand strategy. I didn’t,” Souza told PEOPLE last fall when asked about hisintention behind his popular posts.

“I didn’t even realize what I was doing, to be honest with you,” Souza said while promoting his previous book. “I had to look up what the term ‘throwing shade’ meant.”
