Above and Beyond by Betsy Brannon Green:
Above and Beyond (May 2008) Once they had Caroline safely back, Savannah assumed that she and Dane would pick up where they'd left off years before. But Dane sends her and Caroline to Ft. Belvoir with General Steele and refuses to even answer her phone calls. Then Mario Ferrante's daughter, Rosemary, comes to Savannah for help. Savannah feels sorry for the girl and sees her request as an opportunity to involve Dane in her life again. Dane does agree to help - with near disastrous results.
This is the second book in the Duty trilogy. I really loved the first book but for some reason had a hard time getting through this one. It didn't grab my attention the way the other one did and the only reason why I continued is to find out about the love interest which in my opinion also ran a little dry. You can only hold someone so long with the will they or wont they get back together topic. I am not sure if I will read the last book.
