[T]his is a professional work of fiction that sets high standards, far better than many novels I've read recently. [It] reminded me at the start of a Heinlein juvi and at the end more like an Alan Dean Foster novel.
I have no idea if the science aspect is believable or not but it sure felt believable; more importantly, the science aspect added to the story instead of detracting, a heck of an accomplishment. [T]he book was particularly appealing when it focused on the main character.
