A slow and somewhat confusing build at the start breaks into a sprint that runs off the last page without giving even a chance at a breath. A fun and snappy read, overall, with twists and turns and generally lovable characters throughout. Rielle and Eliana are compelling as dual protagonists, though it almost seems like Legrand was discovering their personalities as we were and, with a couple of exceptions, are pretty similar (though for an understandable reason). The central conceit of the story structure is certainly fresh, and many of the side characters work their way into your heart. It's a great start to a series.
