A/N: This is my first Bones fanfic and it will be a crossover( there is a not so hidden clue )

April 17th 2007 - The day that Dr Temperance Brennan married Special Agent Seeley Booth, little did the happy couple know that in a year to the day their world would fall apart. That day was 4 months ago.

April 17th 2008- It was around 8 pm and Rebecca had turned up with Parker who was going to spend the weekend with Tempe and Seeley for their anniversary. Tempe was cooking spaghetti bolognaise in the small kitchen when she heard a small thump, looking over the oak counter and through the window into the living room she saw her 6 year old stepson sprawled on the couch watching cartoons.

"Hey Parker, are you okay?" she asked concerned as the normally happy and often hyper little boy had a deep scowl on his face

"I'm fine"

"Okay well you better go wash your hands, dinner will be ready in a few minutes" As Parker left the room Tempe realised that her husband still hadn't come back from the front door even though Parker had come in about 5 minutes ago. Putting down the wooden spoon that she had been stirring the spaghetti sauce with she walked out of the kitchen, through the living room that contained the 52' TV that she had been persuaded into buying. Not wanting to interrupt any conversation that night be going on between her husband and his ex she poked her head around the corner first. She reeled back from the sight as a sudden wave of dizziness and nausea hit her. There not 3 m away was her husband in a very compromising position, locked in very passionate embrace and by the look of it a very passionate kiss with Rebecca. She stumbled back to the kitchen then steadying herself on the counter she picked up her mobile that had been left there earlier in case Zach needed to talk to her about the current case. She dialled the number for Cheyenne mountain, Colorado Springs, Colorado.

"Hello, this is Dr. Temperance…" she nearly said Booth the name she had been known by for the past year but in light of current circumstances decided not to use it "Dr. Temperance Brennan, I'd like to speak to Gen. Landry please, thank you. Gen I'd be delighted to take up your job offer. I'll be there tomorrow. I look forward to working with you" She was now glad of the few people skills that she had picked up since her marriage.

"Tempe you okay?" She spun round to see Parker sat back on the couch

"I'm fine" though even to Parkers ears she sounded tired and unsure of herself or her words.

Everything seemed fine through dinner and the rest of the evening. But by morning Tempe had left, taking all her stuff with her and her sleeping husband alone in their apartment with his son who as soon as he woke demanded that he be allowed to call his mum and leave, he didn't talk to either parent for nearly a fortnight- he had seen Tempe leave and had seen the tears rolling down her face as she walked out of the door of the dark apartment in the early hours of the morning.

When Seeley woke to find his wife gone he just assumed that she had already left for the lab, he was wrong. At the lab everyone was giving him the cold shoulder for a reason that he couldn't fathom. By the next day he had twigged that Tempe had left him, for no apparent reason. Within a month following her departure he left the FBI and went back to the Army with his life in tatters..
