Ok, thought I would save some read for tomorrow, I just couldn't. So here I am with a finished book, happy headache and smug face. This is the kind of book, you need to overcome Reader's block and I am writing this listening to Gypsy Danger. :) 
 I can understand the PR strategy behind branding this under the likes of The Martian and WorldWar Z, but to be honest this is more like Deception Point with Jaegers from Pacific Rim. Many might condemn the epistolary writing for poor character development and world building, but author was cleverly desensitizing us from getting too intimate. And kept a more scientific, unbiased and exciting on the edge snazzy accord throughout, now i see where that Martian reference comes from. This seemingly medium sci fi took a political thriller turn at times, not to mention the mushy feelings play in between. Yet managed to keep me on the excitement till the very end ,even with a quite satisfactory ending and after credits. And it also went, a tad Armada(Cline') ish with all that tittah and dhehmeys thingy. Might not be everyone's cup of tea, but I had solid fun, especially when life was going hell, and would eagerly wait for the Teselecta to re appear in future Themis files. 
 This is like Rant in sci fi genre where our Buster Casey is a spoiler. Pretty sure author might be scratching his temple off thinking ways not to muck the premise up in further installments.
