Sign of the times: A couple in Berlin on April 24 strolls by a poster featuring two men kissing. The poster is part of an awareness campaign sponsored by the German Gay and Lesbian Association. It reads, "Love deserves respect" in three languages, including Arabic. In Arab countries, same-sex relationships are strictly taboo. One book that provides a peek at lesbian relationships in Saudi Arabia is The Others, a bestselling novel by a 26-year-old Saudi woman that will be available in English in the United States late this summer.
