I've read Swarm and the others in that series. They are fun pulpy summer time military-adventure-scifi reads. Good page turners without a lot of depth or complexity. I felt a little guilty for enjoying them, but they must have some redeeming qualities as I just keep buying them as fast as they get published!

I think the B.V. Larson books are particularly interesting to programmers as the protagonist is a computer science lecturer who draws a lot of parallels between his challenges "programming" alien technology to meet his needs and programming computers before everything went upside down.
