The Goddess Test by Aimee Carter

Source: Bought
It's always been just Kate and her mom—and her mother is dying. Her last wish? To move back to her childhood home. So Kate's going to start at a new school with no friends, no other family and the fear her mother won't live past the fall.
Then she meets Henry. Dark. Tortured. And mesmerizing. He claims to be Hades, god of the Underworld—and if she accepts his bargain, he'll keep her mother alive while Kate tries to pass seven tests.
Kate is sure he's crazy—until she sees him bring a girl back from the dead. Now saving her mother seems crazily possible. If she succeeds, she'll become Henry's future bride, and a goddess.
Before buying this, I heard just amazing things about The Goddess Test. I had very mixed feelings on it. I really liked the world that Carter created and I found it fascinating. I also liked the twist that this was on the story of Hades and Persephone. The beginning of the story wasn't too engaging, but as soon as she met Henry the story took off and I couldn't wait to finish this book. Kate is a likable character. She is very compassionate and nice. I just didn't get what she saw in Henry and I wish that she had more depth. He was moody most of the time and he cut himself off from her and it didn't seem that he was over Persephone till almost the end. At the end, he seemed charming and sweet, but I didn't really care for him. I liked James a lot more, even though he was the obvious Best-Friend-in-Love character. I could connect to him a lot more. The other gods and goddesses in the book don't seem to have strong personalities, which they should have, because they are suppose to be all powerful. I am hoping that will be fixed in the next book. If the concept sounds good to you, I would read it. The plot was rather exciting and made up for the rather one dimensional characters.
