This was pretty decent. I'm finding a bit more and more a lot of stories just seem to coast on until the end. This felt that way for me until we got to the climax of the book. While I did enjoy it, I didn't find anything truly amazing about this book.
I had gone into this thinking it was YA. Definitely not YA. I kept picturing the main character as a teen (well, she is 19, but I was thinking 16ish). I liked the character, even if she felt a little young for me for a college student. Tristian was interesting. His role was a little more predictable, but not in a really bad way.
I'm not sure I entirely liked the idea of a child being raised ignorant of her family and heritage. It felt a little wrong to me to make someone live to 30 or 40 not knowing why they are so different. Especially when Alexis can't explain why she has to claim her mom as her sister instead.
The ending was interesting. It did leave a bit of a cliffhanger to the point where I knew I would have to pick up the next one soon. I'm just not sure how things will work out after all that is done.
