Viridis is an Ok read with lots of potential but which didn't quite make it. 
 Good point - some interesting spins on steampunk "technology" and a fairly authentic feeling set up of characters and setting. I liked the revolution undercurrents and the descriptions of Lady Phoebe's work with her elixir and club. 
 Could have been improved - I found some of the writing to be a little clunky, particularly the dialogue between the two MC. A really good edit would also have eliminated some of the repeated phrasings. 
 And the bad - The plot was interesting for awhile, but turned into a train wreck near the end. There is (in IMHO) a gratuitous rape scene which is described in more detail than the other R rated scenes in the book and it does little to advance the plot, and left me thinking 'wtf just happened there'. After that I pretty much skimmed to the end. It was a shame really but by that point Lady Phoebe had turned from an interesting headstrong successful businesswoman to a ditzy swooning every 5 minutes idiot who basically offers herself up on a platter for the villain (who then uses her own invention against her). My feminist self was pretty disgusted really at the "dumbing down" of this character, and the way she was turned into nothing more than a plaything for THREE other male characters. The male characters in this book were not victimized by the author, and were in fact more interesting (particularly the Gabriel storyline). The villain being the exception to this comment - sadly, a one- dimensional character with zero motives. 
 I did finish this book, and I think it had a lot of promise but somehow lost its way.
