A Space Girl from Earth (The Kyroibi Trilogy Book One) – Christina McMullen

Ellie Whitmore is no ordinary girl. Even if her parents weren’t internationally famous celebrities, her six foot four inch height and oddly spotted complexion would make her stand out in any crowd. But never would she have guessed she was an alien from far across the galaxy. Or that hidden within her genetic makeup lies the Kyroibi: an ancient and powerful relic housing the forbidden knowledge of her people.

Knowledge some would sacrifice everything to possess.

Worse, it isn’t just the malevolent Emperor who wants the Kyroibi. Her own mother can’t resist the draw of ultimate power and the one person Ellie might be able to trust is an unrepentant assassin who may be responsible for her life’s upheaval. Now, she must travel to a distant planet and unlock the secrets to restoring peace and ending tyranny. But how can anyone expect her to save the galaxy when she can’t even pass organic chemistry?
