     I count a total of 29 titles, but three at least were quite short, and seven were re-reads. Six were non-fiction, 20 were science fiction or fantasy, and three were thrillers. Eight, maybe, are steampunk. Three are short story collections or anthologies.
     One thing I hadn't noticed until just now is that almost all of the novels are parts of series, even if the followup book wasn't released (in some case even conceived) until years later.

     There were only three I outright hated: Homunculus, The Martian War and Fiendish Schemes. On paper I should have liked them.
     Homunculus is one of the first steampunk novels by one of the genre's founders, but while its concepts were interesting, it was a mess. I think I have to give up on Blaylock.
     Fiendish Schemes was also by a steampunk founder, and a sequel to one of my favorite steampunk novels, but this was a very unnecessary book that diminished its predecessor. I can only assume it was done for the money.
     The Martian War was a recursive mashup of H.G Wells' life and his major works and characters, but to little effect.

     Favorites include The Quantum Thief, The Gun Machine, The Constantine Affliction and The De-Textbook.
     Quantum Thief is the first in a series (trilogy?) that mixes hard science fiction and literary playfulness with a a sense of mystery. I'm intrigued. The second book is already out, and number three is scheduled.
     Gun Machine is a police thriller, but a weird one. A routine police call leads to a dead cop and the accidental discovery of an apartment filled with firearms, arranged in seemingly purposeful patterns on the walls, every one of which turns out to have fired the bullets in an unsolved homicide. Who and why? The cop assigned to the car, the partner of the dead cop, needs to solve the case to redeem himself, with the help of some equally damaged forensic specialists.
     Constantine Affliction mixes historical and fictional personages in its Victorian/Edwardian setting (minor spoiler alert: one character is the Frankenstein monster, though he's never called that). It's steampunk without supernatural elements per se (zombies and other-dimensional demons are rationalized scientifically) The title disease sometimes transforms men into women and women into men (when it doesn't kill them), which has the potential to harm the social order as women weren't permitted to inherit titles and estates. It's billed as the first of a series, though no further volumes are strictly necessary.
     The De-Textbook debunks what everybody thinks they know about science, history and other such topics. It's not original (Mental Floss has some similar books), but it bears repeating, and this is an entertaining and informative gathering of such facts.
