Return to Sender [With Earbuds] Book

This book has the distinct (dis)pleasure of being the absolutely worst book I have ever read. If I could, I would rate it in the negative. Like another reviewer said, I love everything that I read & I am really hard to offend. This book is well written as far as grammar goes. The characters are so unlikable, horrible, and their actions so alien to me that it rendered the book unreadable.
Here a quick overview, in my own words, spoilers ahead:
The main female character (magically, I suppose) finds herself pregnant at 17 or so & homeless because of her overly religious father and long suffering yet willingly controlled mother. The father of the baby is a guy from New York that she meets at a Frat Party & has a week long affair with. He is from a wealthy family. Anyway, she's pregnant, alone, and broke. She decides she's going to send the baby's daddy a letter, so she talked to a friend of his & gets an "address" for him. I guess a phone call was out of the question, not sure why. Sure it was before the internet and anyone being just a click away but I would think that their would be a way to find a phone number for someone. Anyway, the letter was written & sent to the provided address. Within a week or so, it was returned by the post office with "Return to sender, Address Unknown". Well, the "Address Unknown" was ignored by the character & I'm thinking it was ignored by Ms. Fern Michaels because the entire story depended on that one detail. So, <1>of course1>, she continues to send further letters to said address, the one that doesn't actually exist, over the years containing information about the child, photos, and baby teeth, etc and of course, they were promptly sent back unopened with Return to Sender, Address Unknown stamped on them. So, fast forward 18 years. She is still carrying around all the letters she has sent over the years in her purse, she is a millionaire herself because she owns a restaurant in a small southern town (lol, I doubt THAT) & her son is leaving to go to NYU. She has become really, really bitter & even more whiny about the stressfulness & heartbreak of being a struggling single mother. As it is repeatedly mentioned, she had to feed her child GENERIC MAC AND CHEESE! GENERIC! She runs into the "baby daddy" at the NYU student welcome dinner. She decides that, <1>imo1> even though she shares responsibility for the pregnancy and she, IMO, owns all the responsibility of the father not finding out about his child, that this man deserves to have a major revenge plot carried out on him. Enter a bitter PI that was fired by the "baby daddy" for being snarky & judgmental when asked to investigate someone & the "fun" begins. Well, fun if you consider stuff such as kidnapping -!literally kidnapping!- the current wife from her home, injecting her with a big dose of Valium, leaving her DRUGGED & ALONE in Harlem in the middle of the night, calling the New York Times to set it up to look like the husband had beat her up, id theft that caused this man to have no access to his bank accounts, credit cards, money, etc., and the general harassment of a man THAT HAS JUST BEEN DIAGNOSED & IS BEING TREATED WITH CHEMO FOR LUEKEMIA fun!!! To me, it was pure insanity and heartless. Not a bit of forgiveness, generosity, compassion, or empathy for anyone but themselves.

So,in a nutshell, Return To Sender is all about bitterness, revenge, and not accepting responsibility for your own actions. Everyone, in their own way, lived happily ever after but did not learn the lessons they needed to learn. They did not really have a change of heart. That would have made this book okay, not great but tolerable at least. When the main character learned of her mistake about the Address Unknown, it was like, Giggle, WHOOPS!
I wouldn't ever recommend this book to anyone I know except maybe my vindictive & bitter ex sister in law.
