Jack Campbell 
The Sister Paradox [EPUB ebook] 

Jack Campbell (John G. Hemry) is the author of the New York Times best-selling Lost Fleet series, the Lost Stars series, and the ‘steampunk with dragons’ Pillars of Reality Series. His most recent books are THE LOST STARS – SHATTERED SPEAR, THE LOST FLEET: BEYOND THE FRONTIER – LEVIATHAN, and the Pillars of Reality novels THE SERVANTS OF THE STORM and THE WRATH OF THE GREAT GUILDS. In May, VANGUARD will be published, the first in a new trilogy set centuries before the events in The Lost Fleet series. John’s novels have been published in eleven languages. This year, Titan will begin bringing out a Lost Fleet comic series. His short fiction includes works covering time travel, alternate history, space opera, military SF, fantasy, and humor.
John has also written articles on declassified Cold War plans for US military bases on the Moon, and Liberating the Future: Women in the Early Legion (of Superheroes) in Sequart’s Teenagers From the Future. At somewhat erratic intervals he presents his talk on Everything I Needed To Know About Quantum Physics I Learned From The Three Stooges, showing how Stooge skits illustrate principles of quantum physics.
John is a retired US Navy officer, who served in a wide variety of jobs including surface warfare (the ship drivers of the Navy), amphibious warfare, anti-terrorism, intelligence, and some other things that he’s not supposed to talk about. Being a sailor, he has been known to tell stories about Events Which He Says Really Happened (but which cannot be verified by any independent sources). This experience has served him well in writing fiction.
He lives in Maryland with his indomitable wife ‘S’ and three great kids (all three on the autism spectrum).
