Elixir

I admit it, I took this book off the shelf because I was like, “OMG, Lizzie Mcguire wrote a book?!” (Along with her ghostwriter Elise Allen.) I didn't expect it to be great, but I tried to keep an open mind. But WHAT THE HELL, this book was so bizarre. It was like a Da Vinci Code/Twilight hybrid, but with no vampires, and with reincarnation. Also I guess I'm that that on GR this is called Elixir #1, not because I particularly want to read Elixir #2, but because my copy makes no mention of this being a series, and the ending (no real spoiler) is like... super abrupt and doesn't really tie anything up??
