[Q]: San Diego (CNN) Twenty-five years ago, Paula Claussen's friend invited her to make the short trip from her home in San Diego, California, across the border to Tijuana, Mexico, to donate clothing to people in need. Claussen didn't expect that day to change the course of her life. The drive took less than an hour, but when they arrived at their destination -- a shantytown on the outskirts of Tijuana -- Claussen couldn't believe her eyes. "I was shocked by the conditions that I saw down there," she said. Families with young children were living in ramshackle homes: The dirt floors turned to mud when it rained. The walls had gaps, allowing tarantulas, rattlesnakes and rats to invade. Many roofs were merely old tarps with holes in them.Paula Claussen visited Tijuana, Mexico, to donate clothing 25 years agoThe poverty she saw inspired her to come back and build better homes for residentsProject Mercy houses replace shacks that often have dirt floors and lack basic amenities

[Q]: (CNN) Balaraba Ramat Yakubu was 12 years old when she was married off. By 19 she was divorced, jilted by her husband; left to fend for herself in Kano state, northern Nigeria. But this isn't a sad story. Instead it's one of community and independence -- from the unlikeliest source. Yakubu began writing. And writing. And writing. The subject she chose was strangely fitting for this child marriage survivor: romance. Soon entire novels emerged. Written and printed in her native Hausa language, they spurred on a whole literary subgenre -- "Littattafan Soyayya" (love literature) -- which years later has grown into a prosperous cottage industry for the women of Kano.Love literature is a burgeoning cottage industry for many women in Kano state, NigeriaSubjects are wide ranging, from tackling child marriage to providing marital advicePhotographer Glenna Gordon has documented the growing craft in a new book
