Too long and slow. Two thirds through this book, the protagonist has solvled the mystery of her mother's death and her father's role in it. The final third, then, is a protracted denouement in which she tracks down the boy she has a crush on. I am not the target audience, but I would have preferred more death-under-mysterious-circumstances and less romantic misunderstanding. Plus one star for repeatedly name-checking Imogen Heap.
