They go through a ceremony in Spanish that Melissa is sure can't be real, followed by a very passionate night. Melissa leaves, thinking she'll never see him again. But after writing a book of sex tips for couples inspired by Antonio, he reappears in her life. Thrown together with Antonio for interviews and book signings, Melissa is having a hard time ignoring his advances. Suzanne Forster's UNFINISHED BUSINESS (3) presents a fun look at a quick, not-so-fake Mexican marriage that unites a romantic hero with a practical heroine.
