Query: A very good first novel

I've read many Science-Fiction novels,and I can tell you, this Author is The Right Stuff! Fascinating and intriguing ideas, exposed clearly, interesting characters, prose fluent and rich, and evocative. You can tell that this is an Author to follow. Voyages at the end of the known Universe, researching the secrets of the Universe structure himself, whilst preventing the resurgence of the worst atrocities so called intelligent beings are capable of perpetrating. Profound and daring, compassionate and learned: my compliments to the Author!
