Velocity Blues

First off, the author is a friend of mine.

The main characters are genetically modified humans who can move very fast.
Not as fast as the Flash, but much quicker than normal.
I pictured Usain Bolt but several times as fast.
And having the metabolism of a hummingbird or a shrew.
The downside is that their minds run really fast as well.
They can't concentrate on anything for more than a few seconds.
This makes it nearly impossible to hold a job.
Even talking to normal people is nearly impossible.
And they have to eat all the time.

The writing gets this across by using many short sentences and frequent changes in the characters focus.
Someone will open a door, go through it and close the door.
In that short time, the characters will have run around the room a few times, eaten something
and thought about 4-5 things, only one of which was important to solving the problem.

There were times while reading this that I felt the need to get up and move around.
The writing style changes to reflect the changing mental state of the characters.
I found this to be effective and clever.

Overall, it's an interesting story, cleverly told.
There were perhaps too many scenes reminding us that the characters were
easily distracted and had to eat a lot.
I enjoyed it and recommend it.
After I finished the book, it seemed to me that the mystery being solved was pretty simple.But it was really hard for the characters because they couldn't think about or even remember stuff for more than a few seconds.This is another way the author gets across what it would feel like to be these people.
