It was okay. I think this is the second Amazon free Kindle First selection that met that criterion. It actually wasn't dire. In fact, it hovered at times between "it was okay" and "I liked it" but it was a bit of a silly read, with a Mary Sue protagonist (other characters stand around her as a greek chorus -- and that is doubly ironic in this book) and talk about how well she handled situations, and how kind and nice she is, and... 
 Anyway, it's basically chicklit, not especially great chicklit, not terribly bad chicklit. It was okay chicklit. Here's the spoiler synopsis: (view spoiler)[Chick gets struck down by supernatural disease. JUST LIKE IN THE FIREMAN. She has an unworthy cheating louse of a spouse. JUST LIKE IN THE FIREMAN. There are a bunch of religious fanatics. WELL SO DID THE FIREMAN, BUT THESE ARE DIFFERENT. She transforms into a new kind of creature (in this case a greek snake-shifter with a perfect figure and a natural need to wear 4-inch heels) JUST LIKE IN THE FIREMAN. She's not pregnant, she doesn't embark on a long journey, but she thinks a vampire bad boy gangster is hot and kisses him. (WHICH IS A TINY BIT LIKE THE FIREMAN) A wiseass version of Cupid flits around and cracks wise. Her grandma is Zeus's exgirlfriend and granny used to be a pistol. LIKE EVANOVICH AND NOT LIKE THE FIREMAN. And no one gets thrown off a boat. Even a little. I kept waiting for a car to explode but it didn't. (hide spoiler)] 
 The worldbuilding is light on substance, high on fetish, and...It's an okay read. There are worse ways to spend a few hours.
