Still processing this one. Long book that will feel familiar to Card fans. A lot going on, a LOT of talking, but still a good read. 
 Two stories proceed as one. Two ships leave Earth at the same time to found a colony on a far-off world. One ship will travel traditionally, with 35 generations passing before their reach their destination. Another ship will take a theoretical leap through time and space and, perhaps, reach the world faster. Some things go wrong, however. As the beginning of each chapter, this part of the story lends some mystery, as we're not sure exactly what is going to happen, or has happened. This is the sci-fi part of the story. 
 The other part of the story, more the fantasy aspect, is a traditional hero tale. The death of Rigg's father sends him off in search for the sister he never knew he had in the city where he was born to the empress who had been overthrown by the revolutionary government. Rigg's training by his "father" has prepared him for many things, but none of it made much sense to Rigg until he's out in the world. His friend, Umbo, tags along and they make the acquaintance of a soldier named Loaf. Rigg and Umbo learn some things about themselves and their special abilities that will help them survive. 
 Split up by circumstances, Umbo and Loaf have to find Rigg, who is brought to the capital city. Rigg meets his mother and finds his sister. He also learns about his real father and the things his father had studied. Rigg makes another friend and, once everyone is united, they travel to their destiny. 
 Did I mention it's a long book with a lot going on? Think I'm going to have to take a deep breath before I dive into book #2 in the series!
