I read about a novel a few years ago that I never got around to reading and I'm trying to find the title. Don't know the author.
It was about a guy's girlfriend or ex-girlfriend somehow turning into a giant and rampaging through a city, and the guy has to also become giant to stop her. Pretty sure the giant woman was called Ruth.
The cover of the book had some giant legs on it. Pretty sure the giant woman was called Ruth.
Note, it was not 'Fifty Feet of Trouble'.
