Antigravity (an Ell Donsaii story #19)

Antigravity is the nineteenth book in a series of near-future hard-science fiction thrillers featuring Ell Donsaii, whose nerve mutation has made her a genius with exceptional athletic abilities. Her inventions have transformed the world, including instantaneous communications and trans-dimensional portals that transport fuel, water, food, energy, and people throughout the solar system. In this installment, Ell and her husband Shan develop a new invention that creates tractor and pressor fields, enabling flight similar to antigravity. Initially appearing to have limited applications, the technology reveals increasingly diverse uses over time. Meanwhile, Zage seeks assistance managing his company, Gordito. Ell helps him establish Gordito Labs, dedicated to continuing cutting-edge bioresearch for humanity's benefit. Ell's twins, Caii and Raii, continue painting and caring for their adopted sister, enjoying tours of Italy's famous art when their parents can take them. As Mount Vesuvius, the volcano that buried Pompeii, approaches eruption, Ell and her company face a new challenge.
