I loved this series and am sorry to see it end so that I will no longer get to spend time in beautiful and fascinating Tuscany with Olivia and her friends. I have to admit that it read like a fairy tale though: after becoming disillusioned with her PR job, Olivia travels to Italy and ends up as sommelier for a prestigious winery, a job for which she has absolutely no qualifications (even though her mother thinks she is just a glorified bartender). She falls in love with an abandoned farm, which is close to her work and just happens to be for sale. She then falls in love with a handsome Italian carpenter and together they discover a treasure map to a hidden underground wine cellar on her property.
Now comes he part that bothered me: suddenly Olivia turns totally stupid (although she has frequently exercised poor judgement in the past by confronting people she suspects of murder). After discovering the hidden wine cellar, Olivia questions whether it is really necessary to put a lock on it, even though she has been told by an expert that even one particular bottle would be worth a fortune. She had made no secret of what they were looking for and is shocked that word of the treasure spread so quickly. Well, duh!
The police are also stupid. It never occurs to them after seeing fallen pieces on the floor of the cave that the victim might have been hit by the stone lying beside him, rather than by their suspect. Once Olivia realized the truth she looks up and sees that the fallen piece fit the gap in the ceiling like a puzzle piece.
Obviously the story has a very happy ending after they all risk their lives to get the wine out before the ceiling collapses. Even huge boulders don't deter them from working in the falling debris to save every last single item, including some huge wine barrels.
