Allison Jennings life is not going well. Her dad abandoned the family when she was young. Mom died when she was 18, leaving her to finish raising her younger brother Ben and put her 18 year old hubby through mechanic school. The marriage to Rusty lasted 2 years. After he left, she discovered she was pregnant with Ethan. Now 10 years later, she's asst. mgr. in the Tasty Freeze, her car just died and her son is turning out to be a science genius. While he's at a 2 week science camp at MIT, her good friend Bunny intervenes and gets her invited to the Needham family July 4th island weekend party. She meets up with Dex Needham, scientist and single member of the family, recently jilted at the altar. Sparks fly, but Alli figures he's too high profile - she just wants an average guy who can pay the bills. The chemistry is too strong though and they end up with a wild night of sex. The next morning she recognizes a birth mark on him - the same guy she had a one nighter with the week after Dusty left. Then she sees a childhood picture of Dex and realizes Dex is Ethan's father, not Dusty, and freaks. His mother also figures it out and tries to buy her off. She leaves, Dex follows, Ethan is his son via DNA, he tries to move them in, she finally figures out he's not so bad and a year later they finally marry. Funny, some sex, good story for the most part.
