I'm usually an average reader, one book takes me 3-4 days to read if I read it every day. However, with A.C.I.D. I read it in 1.5 days, that's right less than half that of most books I've read. It had me captivated from day 1. I only wish that Emma Pass would write a sequel continuing Jenna's story, but even as a stand alone, this is by far my favorite and most recommended book.
