This book is best described as aggressively mediocre. Getting through the middle potion of the book was something of a chore for me. All of the time travel/alternate timelines stuff was kind of high concept, and the author didn't trust her audience enough to understand it.

After Kate was introduced to her time traveling grandmother, she moves into her house and they spend so. much. time. just talking and exchange information. It's an incredible amount of exposition, stuff that is repeated over and over, and stuff that is not presented in any enticing way.

There is a love triangle, but Kate spends so much time talking to her grandmother, we don't get much of a chance to really get to know either boy.

The last few chapters pick up a bit but at that point I was not interested in the outcome.

Kate is an okay protagonist. I really wouldn't know what to say her favor. She's meant to have something of a personality because she quotes movies like The Princess Bride and eats onion rings, but that's basically all I can say I know about her. She annoyed me a few times in high pressure, save the world situations, as she gave to much thought to insignificant, sometimes boy-related problems. I mean, she'd just discovered her father disappeared and was having thoughts like, "but what would this boy help me? I'm just not preeetty." (She was pretty, FYI.)

I guess there will be a sequel, but nope. I won't read on.
