The Tomorrow Log

Meanwhile, on another side of the Universe. . .
Meet Gem ser'Edreth, a wizard with electronics — and a freelance thief. Deliberately solitary, unencumbered by family or friends, he immerses himself in his profession, rising to a pinnacle of skill so exalted that the planetary crime boss seeks him out with a commission to steal. Refusing the commission, of course, is his first mistake.
Gem's hidden past proves an unexpected liability and his plants to leave the planet go catastrophically awry. Suddenly embroiled in interplanetary politics, a potential interstellar war, and in possession of an ancient object of power an an unwanted cousin, Gem discovers that the mysterious Witness for the Telios may hold the key to his salvation — or his undoing.

"All the lovely language they seem to specialise in as well as marvelous characters and a good plot. . .
"It goes on my comfort shelf."
