I read this because I am interested in novels about heroic achievers--architects, industrialists, CEOs, etc. The hero of Skyscraper, Brian Mitchell, is an engineer brought into New York to investigate why the 66-story Zalian Builiding, dropped a window into the street, killing two people. It turns out the tower has far worse problems than it first appears, and Mitchell has to fight to save the day.
What rescues this book from being schlock is that it was written by an engineer and provides lots of details about the structure, which I found quite accessible without an engineering background. Subtract this streak of realism, however, and what you get is a 1970s disaster story, like The Towering Inferno. Characters do not grow and are rather flat, although Mitchell has the energetic charm of a rational man.
I don't mind sex scenes, but unfortunately, the graphic stuff here takes place between the sleazy building owner and his buxom chippy. Eww. I did not need to know so much about her breasts! I would have found it much sexier to read more about Mitchell and his heroine, but that was more discreetly handled.
Read it for the engineering material or for the Irwin Allen-style good clean fun. Literary fiction it's not.
