In Search Of A Prince by Toni Shiloh
Brielle Adebayo is fully content teaching at a New York City public school and taking annual summer vacations with her mother to Martha's Vineyard. But everything changes when her mom drops the mother of all bombshells--Brielle is a princess in the kingdom of Ọlọrọ Ilé, Africa, and she must immediately assume her royal position, since the health of her grandfather, King Tiwa Jimoh Adebayo, is failing.
