John McCain is set to release his upcoming memoir, “The Restless Wave,” in April, Simon & Schuster announced Friday.

The publisher quietly signed up “The Restless Wave: Good Times, Just Causes, Great Fights, and Other Appreciations” in February without a formal announcement.

“This memoir will be about what matters most to him, and I hope it will be regarded as the work of an American hero,” said Jonathan Karp, president and publisher of Simon & Schuster’s flagship imprint.

The book is expected to begin in 2008, when he lost to Barack Obama in the presidential election, and will include his opinions on current events in Washington. He has been a critic of current President Donald Trump: Just last month, he slammed Trump in an op-ed he penned for The Washington Post, referring to him as “a president who has no experience of public office, is often poorly informed and can be impulsive in his speech and conduct.”

For “The Restless Wave,” McCain is working with longtime collaborator Mark Salter and Karp, who worked together on McCain’s “Faith of my Fathers,” which was released in 1999, and subsequent releases “Worth the Fighting For” and “Why Courage Matters.”
