LeBron James is starting to stack up children's books like championship rings ... 'cause the NBA superstar just announced his second piece of work will hit bookshelves later this year!!
36-year-old James has been writing up a storm after he inked a deal with HarperCollins Children's Books in 2020 ... co-authoring a 40-page picture book called "I Promise" last August, which became a NYT bestseller.
Now, Bron is back with a middle-grade level chapter book called "We Are Family" ... which follows 5 friends with completely different backgrounds and ambitions who team up to "save their basketball season and prove that sometimes getting a chance is all it takes to succeed," according to the release.
