"Annie's Baby," is an epistolary and is constructed in a diary format. Annie actually names the diary because at one point in her ordeal, her diary is the only "person" she has to talk to, or thinks it is. The book is a series of dated and timed entries that are written by Annie. Since the entries are written by a fourteen-year-old, there is a youthful and even immature tone to some of the writing. Since she is being raised by an overly protective and religious single mother, Annie is careful not to swear in her entries. When she gets to a word that is obviously one she has been raised not to use, she leaves a blank.
