Showing Solitary Tears (Broken Heart, #2) by JL Redington

Where do you turn when love is not your friend?
Patrick works alone, has always worked alone, enjoys being alone. Kate, too, has worked alone on every mission, and has set her life up in such a way that she answers to no one and lives her chosen life of solitary confinement. Why?
Their worlds collide when the two are assigned by their FBI team leader to work an operation that will put every one of their personal rules to the test. Racing against the clock, they must separate their feelings about love and life in order to solve a case that could kill thousands of people.
Amidst nosey neighbors, terrorists and treachery will they find their way back to the most important part of living? Will they put aside their vast differences, working in sync to complete a mission that could destroy them personally, but save innocent lives?
