This is the standard textbook for studying marriage and the family, unfortunately. It is quite a good introduction with interdiscplinary perspectives from thee authors, but their underlying definition of "family" is inherently flawed. The traditinal "family" definition is not covered, nor are alternatives to contraception and abortion like chastisty and nurturing women who want to keep their baby.
Someone needs to write a similiar textbook without this underlying bias. I hope there is a publisher out there that will agree.
