Really quite cute. 
 Plus, it references Madeleine de'lengle. And not only that, but it talks about the problem in the end with A Wrinkle in Time! It's pretty rare that that happens. But, yeah, they should have seen themselves when they landed in the broccoli. 
 Anyway, that may seem random, so we shall move on. This book was written for middlegrades, younger teens and was entertaining, and amusing with the time travel information. In fact, I'd say that mostly the time travel worked. At least, it worked more than some things read! So, in that matter, I was pretty impressed. Ricki, the ebook library has it, and I'm curious as to what you'd think of the time travel. You may consider picking this one up! 
 So, the time travel wasn't bad, the characters were all right, but they lacked a certain depth. Also, Miranda's character development seemed a bit rushed. One moment she's selfish, and then she suddenly isn't. I feel as if there could have been more there.
