Firefly Lane book review

This past weekend, I actually had one whole hour to myself, and I was able to read outside, uninterrupted, for that entire hour!  I can't remember the last time that happened, and I enjoyed every second of it.  I used that time to finish Firefly Lane by Kristin Hannah. The book tells the story of Tully and Kate, two girls who become best friends at the age of 14 in the 1970s and remain best friends for the next three decades.  Here's an excerpt from the summary on the author's website:

For thirty years, Tully and Kate buoy each other through life, weathering the storms of friendship---jealousy, anger, hurt, resentment. They think they've survived it all until a single act of betrayal tears them apart…and puts their courage and friendship to the ultimate test.

I gave the book three stars out of five on Goodreads for a few different reasons.  My favorite part of the book (and this is going to sound really shallow) had to be all the different descriptions of the clothing and hair styles throughout the years.  I'm definitely not someone who keeps up on the latest fashion trends, but it was fun to read about the high-powered working woman suits of the 80s (complete with shoulder pads):


And popular hairstyles like "The Rachel," from Jennifer Aniston's character on Friends in the 1990s:


Parts of this book were entertaining, and the primary setting was Seattle, which I don't know a lot about, so it was interesting to read and I learned a lot.  However, I didn't particularly care for either of the main characters or their relationship (which is unfortunate, since that's what the book was based around).  Tully is self-centered, prideful, and unapologetic (her rough childhood made her this way, so I get it), and Kate is meek and content to be in Tully's shadow.  Throughout the whole book, both characters yearn for the life the other has (your typical "grass is always greener on the other side" idea), and Kate pretty much lets Tully walk all over her (with brief moments of courage throughout).  All of this wouldn't bother me as much if one or both had been dynamic, but by the end, I didn't really feel like either one of them had changed.  Maybe that was the idea or the goal, and Kristin Hannah wanted to show that they had stayed the same through years of change around them.  I'm not sure.  Also, and I won't give away a spoiler, but the end was hard for me to read because it was extremely emotional and a little too close to something I've experienced recently in my own life.  As I finished the book, I had tears running down my face, and that was not enjoyable to me.

All in all, I enjoyed reading the book as long as I didn't think too hard about it :).  I started The Night Circus by Erin Morgenstern, so I will be blogging about that soon.

Has anyone else read either of these books?  I would love to know your thoughts!
