In this book, Giovanni Bignami, the outstanding Italian scientist and astronomer, takes the reader on a journey through the “seven spheres”, from our own planet to neighboring stars. The author offers a gripping account of the evolution of Homo Sapiens to the stage where our species is developing capabilities, in the form of new energy propulsion systems, that will enable us to conquer space. The reader will learn how we first expanded our activities to reach beyond our planet, to the Moon, and how nuclear energy, nuclear fusion, and matter–antimatter annihilation will enable us to extend our exploration. After Mars and Jupiter we shall finally reach the nearest stars, which we now know are surrounded by numerous planets, some of which are bound to be habitable. The book includes enticing descriptions of such newly discovered planets and also brings alive key historical characters in our story, such as Jules Verne and Werner von Braun.

In the near future, much of the globe wages war against the virtaiyu: a high-tech alien race ? and humanity?s greatest threat. Drafted alongside all other seventeen-year-old males, Kaiba Cassidy prepares for the battlefront and struggles with leaving behind everything he has ever known. Simultaneously, Nassira Arujo works desperately in the Brazilian rainforest to keep her family?s refugee camp safe, and Emily Sursten tries to convince herself that the bliss of Australia can last. Kaiba, Nassira and Emily have no idea that their fates are intertwined until each discovers an Elemental Sphere: a mysterious orb that fuses to their bodies and bestows the capability to control an element of nature. But the trio finds that their new powers come with unexpected consequences, and if they are to keep themselves and their loved ones safe, they will have to fight to prevent the elements from falling into the wrong hands while maintaining their humanity in the process?

"All life in all worlds" -this was the object of the author's seventeen-year quest for knowledge and discovery, culminating in this book. In a manner unmistakably his own, Murchie delves into the interconnectedness of all life on the planet and of such fields as biology, geology, sociology, mathematics, and physics. He offers us what the poet May Sarton has called "a good book to take to a desert island as sole companion, so rich is it in knowledge and insight."
