The Writing Retreat by Julia Bartz
Though I'm writing this in the new year, I actually finished this book on Christmas. I read it in about two days, but once I finished, I needed to sit and think before reviewing it. I gave it 3 stars right away because it kept me turning pages and I had no clue what was going to happen, which definitely makes for an interesting read and deserves credit.
Even weeks later, I'm still not sure how I feel about it. The premise was amazing. I knew it was a thriller but the idea of attending a writing retreat and just escaping real life for awhile was so enticing, especially since I was reading it over the holidays so "real life" didn't even feel like a thing.
