When the Martinelli family chocolate shop display goes up in flames at a Brooklyn street fair, fate throws Alex Martinelli and Mike Simone together. Alex, an ER nurse with a passion for reading her daily horoscope, has several valid reasons not to get involved with Mike, an NYC firefighter. An alliance between a true water sign and a man whose element is ruled by fire makes them an unlikely couple. Even worse is his connection to the man who stole her grandfather's secret chocolate recipe. But the sexy hero always seems to show up when she needs him most. In return for his heroism, Mike only wants two things from Alex: a chance to prove he is her soulmate and her grandfather's secret chocolate recipe. In his quest to get the recipe and win the city-wide bake-off, Mike puts his relationship with Alex at risk. Alex tries to deny her destiny, but Mike is determined to melt her heart.
