Apprentice baker Ivy Culpepper sees art cars everywhere she turns. Besides helping prepare the bread and pastry for Santa Sofia's annual spring event, she's the official photographer, documenting the elaborate cars, outspoken artists, and riotous celebrations. Even her family's in on the act: her brother Billy has been runner-up in the competition more times than she can count—but this is going to be the year he celebrates his win in the victory lane. But after Billy's rival, Max Litman, revs up his bombastic showmanship, Billy is once again set to cruise into second place...until Max is found dead, positioned as a prop in his own art car. The whole town knows there's no love lost between the two men, and Billy is the prime suspect. Now Ivy will have to sift through collusion, deception, gossip, and lies to find out what really happened. But with the help of her octogenarian Watson, her restaurateur beau, and her adopted aunts at Yeast of Eden, she knows she can take the heat.
