Antigravity (#19 in Ell Donsaii Stories)

This is the nineteenth book in a series of near-future hard-science fiction Thrillers. Their heroine, Ell Donsaii, has a nerve mutation that’s made her a genius and provided her with astonishing athletic abilities. Her intelligence has let her revolutionize our world with a number of inventions, including instantaneous communications and trans-dimensional portals that deliver fuel, water, food, energy, and people all around the solar system

Antigravity is about a new invention that Ell and her husband, Shan, come up with. It enables the creation of tractor and pressor fields that can enable one to lift off into the sky, the same as antigravity. At first, it doesn’t seem like there will be a lot of uses for it, but as time passes, they keep finding more and more things they can do with it.

Meanwhile, Zage decides he needs help running his company, Gordito. Ell helps him incorporate as Gordito Labs, aiming to “continue cutting-edge bioresearch to the benefit of mankind.”

Ell’s twins, Caii and Raii, continue their painting and caring for their adopted sister. When they can get their parents to take them, they love touring the famous art of Italy.

But Vesuvius, the volcano that buried Pompeii, is about to erupt again.
Can Ell and her company help?
