WASHINGTON (CNN) - President Obama's sister is joining the ranks of her brother by becoming a published author.
"Ladder to the Moon" a children's book by Maya Soetoro-Ng, the president's half-sister, was inspired by her daughter, Suhaila's questions about her grandmother, the president's and Soetoro-Ng's mother, Ann Dunham.
According to the publisher, Candlewick Press, the story is about little Suhaila who longs to meet her grandmother and has her dream come true when she's met with a golden ladder outside her window to join "Grandma Annie" for a magical journey.
The book is due out in mid-April and is targeted to young elementary school students.
