"I, Nate the Great, have something to say. My cousin Olivia Sharp is almost (but not quite) the world's best detective. I solve mysteries. She's an agent for secrets. You won't forget Olivia. She won't let you."
Olivia sharp is back! Rather than solve mysteries like her cousin Nate, Olivia helps friends with their problems by detecting what's wrong beneath the surface. You'll be won over by Olivia's spunk, eccentricities, and can-do spirit.
