When Charlotte O'Hara finds popular chocolatier, Candy 'Gram' Brown, dead on the floor of the candy shop days before Valentine's Day, she finds the mystery of the woman's death too sweet to pass up.

Former barista turned tree farmer Charlotte O'Hara is struggling. Her mom doesn't trust her. Her boyfriend is keeping secrets, and her old crush, Brian Gold has a new, annoying girlfriend. What's worse, everyone loves the petite, blonde, Ph.D. candidate who Brian met at college. That is, everyone except Char.

When Char travels to Crystal Creek to buy Valentine's gifts for boyfriend, David Moore, she makes a shocking discovery. There's a dead chocolatier in the kitchen of Candy Grams Chocolate Shop. County Sheriff Maynard and Deputy Zeke Simons seem to think that Candy's death is a cut and dry case, but Char has her doubts. A bouquet of flowers with a card signed 'V' is her first clue to solve the crime.

Using David's lightning quick computers and special software, Char begins investigating Candy's death. But she also uncovers a few secrets about her loved ones that she hadn't expected to uncover.

Will a barista turned tree farmer have what it takes to solve the mystery before Valentine's Day? Charlotte O'Hara will certainly try.
