Read it. Liked it. I especially liked the female lead in last book. I recommend it highly.
Except. Buy it so follow Freeper Matt Bracken can be duly rewarded for his hard work.
Wife and I have been doing our part. After buying and reading the series ourselves, we sent three sets out as Christmas gifts last year.
Amazing/scary how these stories are coming true.
The four of them will be mine when I have a regular job.
