Strong for you

I could find a more suitable cover, but it's better that nothing.

This is a sequel to "Soul Sisters"
Sandra and Gabby graduated from high school. Gabby suddenly decides to be useful to her country and serve in the military. Sandra doesn't like the idea because she can lose her beloved sister and strictly forbids her to do so.
Will Gabby obey her older sister? Will she find a safer place to serve her country?

Btw, I know that military works different in every or some countries. So I'm going to mix up a bit,so yeah...
