LeBron James will publish a picture book in August

Need to buy a book for a sporty youngster this August? I Promise should be a slam dunk.

That’s because it’s a picture book written by basketball phenom LeBron James.

I Promise, illustrated by bestselling children's-book artist Nina Mata, comes out August 11, reports CNN.

It’s the first installment of a two-book deal that HarperCollins Publishers announced with the NBA star's LeBron James Family Foundation on Tuesday.
