From Goodreads: Three years ago, Sophie Mercer discovered that she was a witch. It's gotten her into a few scrapes. Her non-gifted mother has been as supportive as possible, consulting Sophie's estranged father--an elusive European warlock--only when necessary. But when Sophie attracts too much human attention for a prom-night spell gone horribly wrong, it's her dad who decides her punishment: exile to Hex Hall, an isolated reform school for wayward Prodigium, a.k.a. witches, faeries, and shapeshifters.
By the end of her first day among fellow freak-teens, Sophie has quite a scorecard: three powerful enemies who look like supermodels, a futile crush on a gorgeous warlock, a creepy tagalong ghost, and a new roommate who happens to be the most hated person and only vampire on campus. Worse, Sophie soon learns that a mysterious predator has been attacking students, and her only friend is the number-one suspect.
I thought Hex Hall was pretty good, not super awesome, but good. I liked Sophie, she was a decent character, not too whiny or full of teen angst. I liked Jenna. She was a fun character, even though she was sad and moody most of the time. I didn't like Elodie or the relationship that she had with Sophie. The evolution of their relationship didn't seem realistic to me, but maybe I'm looking at that from personal experience.
I thought the story line was fairly interesting and the ending twist was kind of a surprise. I did like that this book was lighter than say Hush Hush or Twilight, not nearly so dark as either of those. Obviously this is going to be the start of a series. I'd be likely to pick up the next book in the series to see what happens next.
