A dear friend of mine has just published a memoir telling her love story, which includes the legal struggles she and her partner face as a bi-national queer couple. While telling her story, she weaves in the hidden histories of queer men and women who walked the same streets she and her partner do today.
It's a great book and a quick read and if you've been affected by issues surrounding immigration or marriage you'll find it particularly compelling. I'd go on and brag and say more but I don't want to be done for wanton promotion!
