Is some giantess preventing you from going to Amazon and looking it up?
Here's the listing Note the cover on Amazon is censored, unlike this one. Hmmmmmmm.
Here's the blurb for it:
>A dirty bomb has been dropped and humanity is forever changed. The boys who didn't die stayed the same but the women grew into giantesses—walking gods as tall as the mountains. To remake a new and better world, all post-pubescent men were eaten and killed, and the remaining boys were rounded up to live in The Pen and learn to become better men.
A book by someone who has Issues, for others who have Issues. This goes way beyond snoo-snoo.
