This book was *dreadful*. Several of the assignments refer to signs that aren't shown anywhere in the book; one of the explanations refers to posessive pronouns as "objective" pronouns, which means something completely different; many of the pictures used to illustrate signs are confusing, and there's little attempt to explain them; even the definitions offered aren't always clear. There are plenty of better books about ASL available.
