I would have really, really loved this book if I hadn't figured out the big Potentials plot secret in the same instant it came up in the book. So, the surprise element was kind of spoiled for me, but I still loved the bond between Scarlett and Rosie, and the retelling universe of little Red Riding Hood that the author created. Ultimately, this book is an ode to sisterhood and love between siblings. And Lett is a great kick-ass heroine... Her character alone would make Sisters Red worth reading.
