Lately, life is both sweet and sour for intelligence operatives Mark Vincent and Quinton Mann. The sweet is they’re settling into a relationship; Mark has found a condo in Alexandria with the help of Quinn’s mother, Portia; and Mark and Quinn are looking forward to spending the holidays in the Caribbean.As for the sour, something shadier than usual is going on at Langley. Useless missions and sleepless nights are leaving Quinn exhausted, and then Portia’s life is threatened. When Quinn discovers the accident was no accident and the egomaniacal Senator Wexler is involved, he’s out for blood.To this point, Mark has stayed out of Quinn’s CIA business. But hurting Quinn and those he loves isn’t on the table, so at Mark’s instigation, they set out together to deal with Wexler. The only catch: it’s the first time Quinn will see Mark at his deadly best, and Mark isn’t sure how his lover will react.
