I have just finished reading Moonstruck in Manhattan...
The ending was tragic! She decided to leave and pursue a career in cheerleading, where she eventually married the star quarterback. But he was seeing other women on the side; she eventually found out and cried herself to sleep every night.
I have never felt such pain. The poor girl.
And the hero of the novel, the guy on the couch, after she left him he decided to commit suicide and jumped off a building top. Problem was he hit the restaurant awning on the way down, bounced into the air, and landed in the back of a passing potato truck.
His screams were lost in the din of the traffic as he disappeared.
The reader never does find out where the potato truck was going or what happened to the hero.
The whole book was like that -- one tragedy after another.
So, don't ever be coming to this site and telling me romance novels all have happy endings.
