What happens to a person when the negative side of their personality does everything in its power to overtake the side that barely keeps the person sane? Ella Black suffers from dissociative identity disorder. Bella, her evil twin, comes to life when Ella gets stressed. Bella has progressively made Ella do more violent things, which scare Ella each time. When her parents whisk her away from school mid-day to temporarily move to Rio, she assumes it is because they have figured out she has this disorder which she has been hiding from everyone. But more lies and truths will unfold in this fast-paced, unpredictable novel, totally ingratiating the reader until the last comments at the end. Ella is a believable character, which makes the story all the more twisted. Speaking of twisted, the last few dramatic scenes hit hard, literally. This reader thoroughly enjoyed Emily Barr’s writing and will look to pick up a few more of her works.
