Tony/JJ

Great story with a premise I have not seen before. Tony DiNozzo is actually Major Anthony DiNozzo, USMC who is undercover in NCIS to seek out corruption. In the sixth year of being Agent he meets JJ Jareau of the BAU and falls in love. He eventually receives permission to read her in and this is their story. There is romance, angst, wedding, and pregnancy in addition to the usual bullets, crime and team drama. Very entertaining and one I read before and lost. You really feel for poor Tony who is nothing like his NCIS persona but he is the best at what he does and is a dedicated marine. The author focused on how hard the relationship was and just how many compromises they had to make as a couple which included hiding everything about Tony to her teammates. I wish the author had continued with an epilogue of what happened when the baby is born but all in all a great story with a satisfying ending.
