Knight of South Holland

Calvin Atwood has been the "go to" guy for members of the Kings of the Castle.

Partnering with Daron Kincaid on top-secret projects was great for achieving a career high, but now one new endeavor could put him in danger again. The first assignment as a Knight of the Castle was to create a military shield for the Kingdom of Durabia. No problem, since Calvin had been secretly working on something similar. Huge problem when countries who are at odds with the American government will stop at nothing to get their hands on him. Suddenly everything becomes complicated-including his parents' desire to suddenly pair him up with a former military man who doesn't seem above board.

Now every issue threatens to destroy his role as one of Knights of the Castle, and has Daron and his eight brother Kings questioning if Calvin is up to the task.
