NoHeart is a great story. Charlotte Roote is trying to follow the steps of her mother who was a practitioner of hoodoo. Her first "conjure" made me laugh out loud. She forgot half of her ingredients and tried to bluff her way through. Her mentor was on to her, but still, her attempts to not seem ill-prepared reminded me of the scene from Army of Darkness where Ash is saying the words "Klaatu, verata, necktie!" "I said the words, I did!"
Even though it started on such a promising note, I ended up disappointed with the book. Charlotte came across as too passive to me, in a lot of ways. It seemed like half the time she dealt with things via the ostrich method - stick your head in the sand, ignore it, and it will go away. Infuriating, but still, that's a personal reaction to the character. Far worse was the lack of editing. NoHeart was rife with typos, misspellings, and in a couple of spots I was confused as to what the author was trying to convey. Just as an example, in one place one of the villains, Maria, had her name spelled as "Maris". That's the sort of thing I'd expect even rudimentary proof-reading (not necessarily a full edit) to catch.
Another issue, and this was purely technical - for some reason the text was a gray color on my Kindle. I know it wasn't my Kindle, either. Locations were a crisp black. The chapter names and the the symbol drawn at the start of each chapter were very crisp and dark, but the actual text was just very light. As an aside, I really liked the hand-drawn art at the start of each chapter - it was a nice touch.
Despite its flaws, I still enjoyed NoHeart, and I will probably read future books in the series. I just think that with a little more attention to detail it could have gone from three stars to four and a half.
