Summer daze - Janet Quinn-Harkin

Tia and Tamera are teenage African-American twins who were adopted at birth into different families. Tamera lives in an affluent suburb with her single father, a conservative businessman. Tia lives in the city with her single mother, an outspoken seamstress. When the girls discover each other at the mall one day, they persade their very different parents that they should all live together - with some very funny results.
When perfect summer jobs turn sour, Tia and Tamera find a way out as counselors at a summer camp where they can take all the great outdoors has to offer.
