Interference starts off with a bang, literally. I won't be giving anything away by saying this, as the book jacket reveals it, but the dramatic assassination of the President of the North American Union sets events into motion that turn a science fiction novel into more of a suspense/mystery, and Blackstone definitely keeps the pages turning. However, that's not saying it's not science fiction!
Some fascinating ideas Blackstone has written into Interference. The Kingdom, man-made terraformed area in the far northern reaches of the North American Union, populated supposedly by backwater barbarians. Sonic shields that snap into place at a threat detection. Mech assault robots with impressive weaponry. Cloning and genetic engineering to create better and better humans. Floater vehicles that can be shut down by command of authorities, or tasked to hunt. Blackstone weaves the ideas well into the overall story, never overemphasizing them, and perhaps more importantly, never violating the "Show, Don't Tell" rule.
I found the story to be compelling, and I was actually more drawn to the character of Detective Henry Corvasce as opposed to Damien Reyes, the one blamed for the President's killing and the one each chapter starts off with (Reyes being interrogated in a unique fashion - interrogated for lack of a better term that might give away part of the storyline). Corvasce made for an excellent main character; deep, well-written, believable, and likable. If another story is to follow, I hope that Blackstone brings back Corvasce as the primary character in another mystery-type setting.
Sections of the story do get very complex at times, as Blackstone has certainly done his homework on quantum physics and mathematics, but no so much as to get lost in. The book was well-edited; minuscule typographic errors, I don't even think I can count them on one hand, and certainly far fewer than I've seen in mass-market novels. My only comment (because gripe would be far too strong a term) would be the 'interrogation' at the beginning of most chapters is all dialogue in quotation marks, and with some of the dialogue being multiple short statements, I did find myself having to read back a few lines to really determine who was speaking. But that in no way whatsoever took away from the overall mystery/suspense story, the excellent characters, and the resolution at the end I was very much looking forward to reading.
Blackstone has put out a good story - entertaining, good characters that are well-developed, an intriguing political mystery with science fiction settings and technology. I can certainly recommend Interference.
