Talk about books with unexpected twists and turns, and you've got to mention The Goddess Test by Aimee Carter. If you think you've heard every take on mythology out there, I think this one would still surprise you.
In The Goddess Test, Kate Winters has moved to Eden, her mother's small town childhood home, because this is her mother's dying wish. Kate's mother, Diana, is suffering from cancer, and her time is growing short. Diana and Kate have always been together, each relying on the other for everything. Young Kate has given up nearly all normalcy of life to care for her ailing mother.
However, when the two return to Eden, Diana insists Kate take part in normal life. She should attend the local high school, and she should make some friends. Kate does her best to do this. She makes an impression on a few of the locals and catches the eye of jealous, teen queen, Ava. When Kate heads out to a party with Ava one evening, everything changes.
Ava dies in an accident that night. However, she is brought back by the mysterious Henry if Kate will agree to grant him the condition of his choice. Of course she does. However, the twist comes in when Henry actually turns out to be the Greek god, Hades. Unexpected! Just as in the myth of Hades and Persephone, Henry requests that Kate be willing to spend the six cool months of the year with him. But, in order to keep this arrangement, Kate must pass a series of tests. If Kate can do this, she will be granted immortality, be able to see her mother in her pre-illness condition, and spend half of the rest of her existence with Henry.
At first Kate is overwhelmed and feels trapped, but oh how things begin to change. There are so many unexpected twists to the plot of this story. I absolutely loved reading it. I can't wait to read the rest of the trilogy. The next book Goddess Interrupted is available now. There is novella called "The Goddess Hunt" which happens between the first two books and another called the "The Goddess Legacy" which is between the second and third, and is collection of short stories told from the point of view of a variety of characters in the series. I am sure these will be great too. This one is certainly worth your time.
