I picked up this book at a free little library and had no idea it was the second book in a series before finding it on Goodreads. That said, I don't think the first book is necessary to read in order to read this one. I will admit, I definitely felt too old to read this book and am likely about 10 years older than the target age range. And the book's age, having been published in 2009, definitely shows. Phrases like "the Internet" and "Web site" made me cackle while reading.
When it comes to the actual content of the book, not much really happens. Ari learns a few things and goes through a few experiences, but nothing ever felt riveting and it never felt like a page-turner. I stuck it out since the book is less than 300 pages, but it was unsatisfying to not have much solved and for most revelations to be mentioned for a few paragraphs, maybe a page, and then to never be brought up again.
The biggest gripe I had with the book, as well as with Susan Hubbard, is the complete and total acceptance of writing a 14 year old dating a college student whose age we never know, but could easily be between 4 and 8 years older than her. What was even worse was Susan writing an adult, political figure openly flirting with said 14 year old which included, but is not limited to, him inviting her on a boat and island with him.
It doesn't matter that Ari was pretending to be older than 14 or that she looked older than her age. Susan wrote these into the plot intentionally and it was abhorrent. Sure, a real life 14 year old might not bat an eye when reading this book, but to so openly normalize such relationships is disgusting.
What keeps this book at 2 stars for me is the concept of vampires and the lore behind them, but that's about it.
