Dangerous Grounds #1: Special Agents for the Department of Diplomatic Security, Taylor MacAllister and Will Brandt have been partners and best friends for three years, but everything changed the night Taylor admitted the truth about his feelings for Will. And when Taylor was shot a few hours later, Will felt his reluctance to get involved was vindicated. For Will, the team and the friendship have to come first--despite the fact that he hasn't failed to notice just how...hot Taylor is.
Taylor has been in love with his partner and best friend since they were first partnered. There isn't much he wouldn't do for Will--but he doesn't know how much longer they can stay teamed feeling the way he does. Still, he agreed to a camping trip in the High Sierras--despite the fact that he hates camping--because Will wanted a chance to save their partnership.
But the trip is a disaster from the first, and things rapidly go from bad to worse when they find a crashed plane and a couple of million dollars in stolen money. With a trio of murderous robbers trailing them, Will and Taylor are on dangerous ground, fighting for their partnership, their passion...and their lives.

Old Poison #2: Happy Birthday, Taylor! Taylor has pretty well recovered from his shooting, but not everyone is happy to see him reach his next birthday. Does a cobra pickled in a bottle of wine means someone cares enough to send the very death -- best?

Blood Heat #3: Special Agents for the Department of Diplomatic Security Taylor MacAllister and Will Brandt have been partners forever and lovers for three months, but their new relationship is threatened when Will is offered a plum two-year assignment in Paris.
Will believes the posting only means postponing what they both want. Taylor fears that kind of separation will mean the end of their new and still-fragile relationship. It's a bad time to find themselves in the middle of the New Mexico wilderness responsible for the health and welfare of a suspected terrorist. Especially when everyone else they run into seems determined to see their prisoner - and them - dead

Dead Run #4: The boys are back in town -- and Paris is burning!
For Special Agents of the Department of Diplomatic Security, Taylor MacAllister and Will Brandt, the strain of a long distance relationship is beginning to tell after eleven months of separation. A romantic holiday could be just the thing to bridge the ever-growing distance, but when Taylor spots a terrorist from the 70s, long believed dead but very much alive, it's c'est la vie.
Now instead of sipping wine and seeing the sights, the boys are chasing a wily and deadly foe through the graveyards and catacombs of Paris.
Of course, it could always be worse -- and soon it is

Kick Start #5: Will is finally braced to bring Taylor home to meet the folks. Unfortunately, not every member of the Brandt clan loves Taylor the way Will does. Then again, not everyone loves the Brandts. In fact, someone has a score to settle -- and too bad for any former DS agents who get in the way when the bullets start to fly.
