Prince of the Sun, Princess of the Moon — M.R. Anglin

For years the Moon Palace in the Valley of Aijalon and the Sun Tower in the Plains of Jashar has stood as testaments to the power of the sun and the graciousness of the moon. Helio and Lumina, Guardians of the sun and moon, kept watch over them and the Prince and the Princess who ruled them. But the Prince and Princess are missing, and the sun is exhibiting strange behavior.Now Joshua and his younger sister, Deborah, must untangle a web of lies and deceit to uncover the secret of who they really are and save their world from an imminent disaster brewing in the heavens. And they must hurry. Between the earthquakes, the sun and moon standing still in the sky, and the planet Jants hovering closer than it's ever been, the planet could be torn apart before they have a chance to do something about it.
