Gideon has going out with Shirley for two months. She's principled, strong-willed, and beautiful. He enjoys her company, and hopes that one day she will agree to make their relationship official.

But there's something he's not telling her. A secret so terrible he's afraid of what she might do if she finds out. When the moon is half-full, Gideon changes into a creature of the forest: a vicious, bloodthirsty werebear.

Can he keep his secret for long? And if he doesn't... will she ever accept him as he is? And if she does, will his... animalistic urges be too much for her to handle...?
