A Space Girl from Earth

Yesterday, her biggest worry was failing an exam.
Today, it's saving the galaxy.
From her six foot four inch height to the uniform white dots that peppered her skin in perfect geometric patterns, Ellie Whitmore was certainly unusual, but an alien from the other side of the galaxy? Of course not. That's just what the tabloids said to sell papers.
Or so she thought.
Turns out not only is Ellie an alien, but an ancient and powerful relic housing the forbidden knowledge of a lost civilization is hidden deep within her genetic code. Suddenly she's on the run from a malevolent Emperor who sees her as the key to ruling the galaxy. Even 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?
