I was pleasantly surprised by this free book on Amazon. The characters are real and believable, and the book is well-written. It held my attention and kept me wanting more. As far as science fiction genre, this book contains elements of hard sci-fi, including dealing with issues of gravitation and language barriers between species. However, it does incorporate more fanciful elements, like faster-than-light travel and highly evolved/ascended beings. It's not space opera but it presents a great first contact type of story. It's definitely worth a read.
