Editor's Notes & Price Research
An addictively suspenseful and tautly written thriller, The Good Girl is a compulsive debut that reveals how, even in the perfect family, nothing is as it seems. This is the unabridged version and listening length is about 10 hours and 38 minutes.
An account is free. It allows you sign in (I think with your Amazon password?), and you can access all Audible books that you "bought" in the past, whether you paid money for them, got them free, received them as a gift, transferred them from another account, etc.
A membership is a subscription that allows you to earn a credit for 1 or 2 books a month; you trade those credits for books of your choice. (Typically all or almost all books they offer, regardless of price.) The current normal price for a membership is $14.95 for their 1-book-a-month plan. With an account, you can buy books (at fairly high prices, for most slick dealers) when you want, but there is no obligation to do so.
Via your account, you always have access to all books in you account, even if your membership lapsed, or you never had one.
So, for this deal, you want to sign into your account, and "buy" the book for $0.00; you don't want to start a 30-day trial.
