Tom Brady‘s new self-help book won’t be published until September, but it’s already an Amazon bestseller.

The New England Patriots quarterback announced Thursday he was writing “The TB12 Method: How to Achieve a Lifetime of Sustained Peak Performance,” and by Friday afternoon, it had moved to the No. 2 spot on Amazon’s bestselling books list.

The book will be available in hardcover, e-book, and audio editions.
