Ethan Hawke's Rules for a Knight to Hit Bookstores This Fall

Ethan Hawke, the author of two novels, is returning to bookshelves for the first time since 2002.

Rules for a Knight, due out this fall, will cap off a year that has included Hawke’s debut documentary (Seymour: An Introduction) and his fourth Oscar nomination (for Boyhood). Per Hawke’s publisher, Knopf—who shared details of the book exclusively with TIME—Hawke originally wrote Knight, a parable, as a gift to his four children. The publisher’s synopsis further reads:

“A knight, fearing he may not return from battle, writes a letter to his children in which he tries to leave a record of all he knows. He lays out the truth of the world as he sees it in a series of ruminations on solitude, humility, forgiveness, honesty, courage, grace, pride, patience, generosity, authenticity, and love. He presents an honest and joyful accounting of what the measure of our lives should be.”

In a recent interview with TIME, Hawke spoke about his evolution as an artist. “When I was young, I just had a tremendous amount of—joy is one word, hubris is another. I was just so excited to be a part of of anything creative,” he said. “‘I wrote 10 pages. Look! You should read it.’ And now as you get older, you’re like, ‘Okay, wait. There’s a lot of things you should read before I’ll waste your time with [my work].'”

That concern has evidently been overcome with a story that’s intended to speak to young people, and that’s explicitly intended as advice: Hawke’s publisher compares the book to Ralph Waldo Emerson’s “Self-Reliance” and Anne Morrow Lindbergh’s Gift From the Sea. Like his character in Boyhood, Hawke, writing for his kids, is growing up.

After all, as the book instructs its reader: “A great knight uses his power to empower others.”
