Lydia, a waspish high born girl, is furious that Prince Edward of Thais is about to marry her worst enemy, the low born spy girl, Mel. So, she does what any determined girl would do – tricks Edward into marrying her.

In the meantime, Mel discovers that her evil ancestor, Mordred Darkthrop, has passed down his most precious possession to her: a magical orb with the power of death. Wanting nothing to do with her wicked ancestor, Mel must now seek out the orb and destroy it, before someone else with the power to use it discovers its location. Edward happily comes along to escape his life with Lydia.

Edward and Mel adventure to a new continent with old friends to find and destroy the Orb of Death. Along the way, they will meet new friends who wish to help them on their adventure.

The Lost Orb is part 3 of the Orbs of Magic series.
