i had a different experience with this book than most because i just immediately accepted that the cat was immortal (or at the very least like, 27 years old) and continued reading.

really liked the time travel/parent-child relationship/best friend in any timeline/teenage girl aspects of this book, but the writing was a little lagging at times and i felt like the ending could have given more in terms of emotional impact. also, if you don't know a lot about NYC, prepare to be confused and ambivalent about a lot of travel/location description!
