They were inseparable. Only Kate could coax her astrophysicist grandfather to stop slaving in his laboratory long enough to enjoy picnics in the garden. And only Grandfather's gentle humor could lift Kate out of her doldrums. His rambing New England kitchen was more home to her than anywhere else. Yet now something was different. Nobody--not even Kate--could get Grandfather to talk about his latest experiment. Only when a strange, otherworldly visitor nearly destroys the laboratory does Kate learn the truth of why Grandfather has been working so feverishly to identify a mysterious connection between the nature of light and the nature of the human soul. But before Grandfather has explained everything, he suddenly disappears--leaving Kate to search for him and for the secret that could save the planet Earth and the entire solar system from annihilation.

Heartlight is a quest with the highest possible stakes, a tale of mystery and adventure that will be enjoyed by readers of all ages. It is the story of the extraordinary bond between a young girl and her grandfather, and an eloquent statement about the ability of one individual, armed solely with the power of love, to change the course of the stars.
