I have a crush on Tristen. LOL. In my opinion, Beth got him just right. The mix of hot guy battling with dark side, and he is a musician to boot. I also relate with Jill since she is shy, insecure and smart, and as the novel progresses she grows into herself, partly because of Tristan, helping and being there for him, and partly because of coming to terms with her father's murder.Minor spoilers- However, I hate how she so easily gave into taking the formula, and her little outburst with the chemistry teacher.It did tie up nicely in the epilogue and give me a HEA, which I love.
