It's Christmastime in Boston, and this year the silver bells will be wedding bells as FBI agent Jules Cassidy ties the knot with the man of his dreams, Hollywood heartthrob Robin Chadwick.

The pair plan a quiet, intimate ceremony, to be witnessed by family and close friends from the FBI, SEAL Team Sixteen, and Troubleshooters, Incorporated, including Sam Starrett and Alyssa Locke. But the holiday season brings more to the happy couple than they expect.

A waterfall coming through their kitchen ceiling, a bat colony in the attic, old family tensions'even an international incident can't dampen their spirits. But add to that a parade of unexpected guests, including a reporter looking for a scoop, an ex-lover hell-bent on causing trouble, and a dangerous stalker, and suddenly the wedding is poised to unravel in chaos.

But nothing will stop Jules and Robin from getting their happy ending, because along with a guest list featuring the most elite counterterrorism force in the world, they have their own secret weapon - true love.
