Introductory astronomy books usually follow two broad paths: descriptive or mathematical. This book is fundamentally a mathematical approach but with a difference. Dr. Lawrence has written text and computer programs which emphasize concepts rather than derivation of formulas. You do not have to be a mathematical wiz to read and learn from this book.

This book is about optimism and hope. Drawing from a collection of true stories, it takes the reader on a journey of exploration to reflect upon the amazing world in which we live and to meet some truly remarkable, sometimes quirky, people along the way. Above all, this book is a journey of introspection that encourages us to sing with fervor and sincerity, even when the voices that whisper to us in our darkest moments suggest that we do otherwise.

Kate Smith spent years controlling her gifts of telepathy and compulsion. Over time, she created different personalities, her masks.

A young girl has disappeared, and Kate knows there is much more to the story. They enter a race against time to save the girl and themselves.

Mask of Emotion (Path to Destiny)

Every four hundred years, an all-powerful being is born. Known as the Mystic, this magical entity must maintain the balance of all realms and save the world in an ultimate battle. For those within the magical realms, the role of the Mystic is legendary. However, the Mystic has been born in the human realm. She’s not only unaware of her unique destiny, she’s missing. Time is running out. Even if she’s found, no human has ever stood against a demonic realm and lived. FBI agent, Kate Smith, has spent her entire life hiding from her psychic abilities. As much as she despises being different, she admits they’ve helped her solve some of the most brutal cases. But her latest assignment has her doubting herself. It’s like nothing she’s encountered before, and the gifts she’s grown to rely on aren’t working. Visions haunt her dreams, and questions about her destiny plague her. Worse yet, the answers she discovers are even more terrifying. For twenty-eight years, Xander Montgomery has searched for the only being who can save all realms. But it’s not easy finding someone unaware of who she is, and being stuck in the human realm isn’t helping his disposition. As a Guardian, he has one mission—protect the Mystic. When Kate and Xander finally meet, he’s convinced of one thing. If he can’t persuade the strong-willed stranger to follow him on a deadly quest, the world is doomed.
