Tunnel Vision really excels from a plot perspective. I called an early twist, but everything else was really surprising. Adrian took a lot of chances, and she made the book a bit darker than I'd anticipated. Shit gets real for Jacob, and he has to make some really terrible calls. Tunnel Vision really rolls around in the ethical gray areas, and I absolutely love when books do that.
The science fiction elements were quite strong too. Jacob Lukin has the ability to "tunnel" when he touches an object of value to someone else. What that means is that he can see that person down to their precise location and current activities. It's pretty clear why that talent would be appealing to government agencies, huh? I found both the concept and execution of tunneling really cool. My only qualm here is that he occasionally was able to tunnel with objects that were not special to the person or of great importance, like a tiny piece of cloth torn from the tag on a pair of shorts, which felt like it didn't fit with the book's own internal logic.
I thought Jacob's relationship with his sister was really sweet, as was his bond with his grandfather. Some novels fail to sell the familial relationships because plot gets in the way. Jacob never forgets how much he misses his family, and that made the situation feel much more believable.
What Left Me Wanting More:
The characterization wasn't the strongest point of the book on the whole, but it will work for anyone who isn't firmly a character-driven reader. The really weak aspect is the romance between Jacob and Rachel. Her character feels very much shoe-horned into the story to add romance. Now, I love a romance as we all know, but it frustrated me here because her character served no other purpose. Jacob's really not in a position to be in a romance in Tunnel Vision, but it's forced in there anyway.
The Final Verdict:
Tunnel Vision will be a great read for those who love reading about spies and an awesome plot. Character-focused readers, like myself, might find a little something special here too.
