Cygnus Rising: Humanity Returns to Space (Cygnus Space Opera Book 1)

by Craig Martelle

From space they came to space they returned. Humanity would not be denied.Reviewers had this to say:"Old-fashioned space opera. Good guys, bad guys and only a bit of romance to add to the characters.""This is a great "start point" for people who do not read the original books. Taken from the start of your MC coming into Boot Camp and flowing through all the fun and team-building games played there. This will help others to see the characters in their strengths and weaknesses as individuals. I enjoyed that the other characters had a chance to shine too.""Readability... very smooth with good transitions from scene to scene. Build-up was gradual and the philosophy of the parent planet's drive to explore seemed very natural. Failures were also points of learning for the society and the blendin...
