The premise of the story started out interesting when you first meet the narrator, Hannah Martin. Though her life splits into parallel universes at a pretty random juncture: the choice to stay at a bar with an old flame, or to go on home.
The events that ensue from both choices tend to be pretty flat and predictable, particularly the ones that happened in both versions of Hannah's life, and I found myself bored at the halfway point. Hannah Martin herself wasn't all that interesting, I found her too shallow and emotionally immature to carry an entire book.
The story lost a lot of steam and didn't really make as much of the question of fate and destiny as it could have. It felt like a rather shallow treatment of what really was an excellent premise. Very different from AFTER I DO.
I give MAYBE IN ANOTHER LIFE a C+, but I'll definitely continue reading Taylor Jenkins Reid. I'm just glad this wasn't my first introduction to her, or I probably wouldn't want to read anymore.
