This book is so engaging that I'm willing to overlook a few minor annoyances. Like most YA books I've read, there are a couple of overused tropes here and there. Yawn, another love triangle. Yawn, the male love interests are just so protective. Yawn, the main character complains about being pale-skinned and thin, as if those are attributes considered unattractive in our society. 
 But all in all, it's a pretty good read! There's futuristic partying, dynastic political scheming, and some interesting re-imaginings of our current reality. I found myself excited to see what each new dimension would bring: how historical events and technological progress would differ, how the next iteration of Marguerite might deviate from the last. Marguerite was a likable narrator, and her emotional reasoning made sense to me. Between all the dimension-hopping, there's time to mull over ideas of fate, individuality, adulthood, and finding truth in art. 
 A Thousand Pieces of You is probably the ultimate nightmare for anyone suffering from Capgras delusion, but it's a load of fun for the rest of us! I've already put myself on queue at the library for the sequel.
