Timelord

Mac, an interstellar merchant, engages in various adventures alongside an unexpected passenger, the wise and beautiful Gracia, and by chance finds a way to travel back in time with his smart spaceship to correct something horrible that had happened in his past. On their way they will have to deal with a super smart and evil dictator on a space station, travel through the anti-universe, visit California in the mid-20th century, meet some aliens, and try to stop the terrorist who caused the worst tragedy of Mac’s lifetime. Easy reading, with a little humor sometimes, you won't be able to leave this book until you finish it...
