The romance: The book tries so hard to deny that this is insta-love by claiming that Tessa hates Dastien, but yet she still thinks about him and is attracted to him the whole time. So....kinda fails at it. Definitely felt like insta-love to me. Ugh. No real love triangle to worry about though, kinda, so I guess that's nice...
I'd say this is a book geared much more towards to early college late high school audience, though anyone who loves the YA shifter genre could probably enjoy it.
