When humanity has been evicted from Earth for the good of the rest of the inhabitants, the remaining colonists on the eight worlds can cope by being Heinleiners, or by role-playing a seedy noir detective and solving mysteries. Chris Bach and his uplifted dog, Sherlock take a case from a woman who was deliberately infected with a disfiguring disease. 

In a world enlarged by augmented reality, where smart clothes and smart lenses add layers of context and metadata to your experience, those who came to this experience late in life are at a disadvantage compared to the younger generation. Our foil in this story is Robert Gu, recently cured of Alzheimer's, who is struggling to re-integrate with this society. His children and their friends introduce him to this world, with mixed results. One symbol of this change is the effort to digitize all the works in the University Library – an effort that will free the world's knowledge to be used by all, at the cost of destroying the books themselves. 

​Singularity Cyberpunk, caged gods and their obligate worshipers, a satisfyingly complex con job and grand heist, and an epic space battle. The execution is outstanding, the pacing is excellent, and the characters have distinct and interesting voices. On top of all this are meditations on what it means to be human, carried on from the points of view of four engineered lines of specialized humans plus the baselines, to say nothing of the AI that believes it's the reincarnation of Saint Matthew. The character arcs for the main players were all satisfyingly developed. A very satisfying read.

Implied spaces are those unintended elements that exist, just because something has to fill the void between the spaces that are deliberately created. This metaphor starts with architecture, but the swordsman and scholar Aristide extends it to the created worlds, societies, and pocket universes of post-singularity humanity. He discovers a plot emanating from the implied spaces that threatens to destroy all that he created, from a nemesis who can match or exceed Aristide's nearly god-like powers.

Any book that has an occupation of 'coincidence engineer' has something going for it. Undertow has some interesting propositions to set up its world: instantaneous interstellar travel but only for non-sentient matter; people have to take the slow boat. Quantum uncertainty that can be manipulated on the macro level to create 'luck'.
