A mysterious artifact found during an archaeological dig in New Jersey has the power to drain the size and strength of men and bestow it on women! A group of female grad students, their friends, and miscellaneous women who cross their paths, find themselves growing bigger and stronger as various men begin to dwindle.

"This year, give the woman in your life the gift of muscles!"

Recently-engaged Don invites his sister Grace to his home for Christmas, but the formerly skinny young woman has become as muscular as a linebacker and as strong as an ox! Grace's strength doesn't come just from lifting weights, though, because she's discovered an ancient relic that can transform any woman into a muscular amazon in just minutes, and the stocking-stuffer she's giving her girlfriends is turning them into sleeve-stretching muscle girls –– including her future sister-in-law! Can an ordinary guy like Don handle it when his sister, fiancee, and even female co-workers become suddenly-jacked and incredibly strong?

This story contains female muscle growth, amazon transformation, mixed arm wrestling, women outmuscling men, and a bit of male shrinking. It occurs in the same universe as classic female muscle growth story "The Amazon Artifact", but is not a direct sequel.
