The book is Alex J. Cavanaugh's "CassaStar", which is releasing world-wide today.Though officially categorised as Science fiction/adventure/space opera, something tells me the book has enough 'coming of age' undercurrents to appeal to the reader of YA also.
Don't take my word for it. Check out the trailer-
