I liked the book for the most part - the behind-the-scenes tour stuff was great, loved Jake and his motley roadie crew. I even was cheering 100% for Rielle. Because of that, though, I had a lot of trouble forgiving some of her actions and I thought other characters were too forgiving as well. The ending has left me very unsettled.
That said, I really enjoy Ainslie Paton's books and am looking forward to reading DJJ later this summer.
