I had a whole lot of problems with this novel, which was fortunately short enough, and engaging enough (I guess?), that I avoided DNFing it.
Here are just a few, in no specific order:
*** CAUTION SPOILERS AHEAD ***
1) the blood test and every interaction the main character, Brock Hobson, has with the company that provides it, make absolutely no sense. It's not just that the whole thing is impossible, technologically -- in fact, that's the least of the problems 'coz you just have to think of it as spec fic and go with it. No, it's that Brock holds deep suspicions while he simultaneously allows himself to get repeatedly taken in and, really, bullied by the con. Much is made of Brock's predictable, insurance-adjuster personality profile. These two things don't go together. There's no motivating event for this dip, by Brock, into devil-may-care personal (and financial) profligacy. This is especially true because nothing else in his life changes, even though ...
2) his girlfriend/wife-to-be points out he's changed during a completely bizarre visit to a forest glade where she has a Snow White moment feeding deer and birds by hand while complaining that Brock is not the Brock she used to know. There's no indication of this manifested in his behaviour as described in the novel; we know he is struggling internally with the test results and resisting what they forecast, but this does not appear in any kind of changed behaviour that would be evident to anyone around him. In fact, the opposite is true in that his family point out how he continues to be more likely to clean out the garage than kill someone.
3) two repeated motifs became unbelievably grating: how everyone gets his name wrong (Really? Hobson is so unusual? No. And why?) and Brock's propensity for correcting everyone's grammar -- this last one he mostly gets right but sometimes gets wrong, e.g. he calls someone Dr. Kenneth G. LastnameIdon'tremember, Ph.D. (Dr. OR Ph.D., Brock, not both). And the biggie:
4) the blood test results don't give you an ALIBI. They could potentially give you a reason, a rationale, an explanation, background context, maybe if you stretch it exculpatory evidence ... but NOT. AN. ALIBI.
This bit about the misuse of alibi, repeatedly, by a guy who corrects other people's grammar, pissed me off so much I'm now going to reduce my rating to 2 stars and stop writing this. And I haven't even got to the stupid, non-sensical, and unbelievable "DUAL" -- okay that was a little bit funny, I confess.
Before you lambaste me for reading too shallowly, I get that he was taking on pre-determination versus freewill, but m'eh. The story was too flimsy and ridiculous for it.
Still, I'll keep that second star because there was something a bit charming about Brock -- his innate niceness, kindness, and goodness. He reminded me a little of Bob Comet in Patrick deWitt's The Librarianist.
