Born in New Jersey, but grew up in San Diego, Omololu was almost 6 feet tall by the time she was twelve. Except for a book called How the Rabbit Got His Hop that she wrote in third grade, she didn't write anything unless she had to. Every diary she ever had stops on or about January 21st because she got bored writing about her own life.
She met her husband when working for a San Francisco weekly newspaper (in advertising, not writing).
She became a stay at home mom for a few years and then noticed that there weren't enough biracial kids books and so she decided to write one. "When it's Six O'clock in San Francisco" came out in July of 2009.
Then she decided, even though it would be really hard, she would try her hand at writing a novel. She met her agent, Erin Murphy, in an elevator at a writer's conference and when she finished her first novel, they signed together. Her young adult novel Dirty Little Secrets came out with Walker Books in February of 2010.
