Gamer Girl is the story of a teenage boy who, after reluctantly agreeing to help his older sister by letting her make him up as a project for her college course, finds himself inadvertently presenting as a female in an online computer game.
Thoroughly enjoying the experience, he returns to the game at a later date and joins an all-girl 'clan'. It's only meant to be an innocent bit of fun after all, if anybody realises he's a boy, he can just sign out and never go back, with no harm done, right?
However, it soon becomes more complicated than that, with higher stakes to play for.
