Abandon - Blake Crouch
I just finished this and I liked it but not quite as much as the other books of his I have read. Blake did something interesting by telling two stories simultaneously, one set in 1893 and one set in 2009. The books starts off in 2009 with a group of people hiking into an old abandoned mining town in Colorado. In 1893, all of the residence of this town disappeared and it was a big mystery as to what happened to them. So, the book tells both stories alternating between 2009 and 1893. You get the adventure, thriller story of 2009 and the entire mystery of 1893. The problem I had with this book is that the 1893 story has a lot of characters and by alternating the story every few chapters, I struggled to remember the characters from 1893 when I switched back from 2009. After the half way point, it got easier but the back and forth made it hard. This is almost like two separate novels. If I ever read this again, I think I will read all of the 1893 story first in it's entirety and then the 2009 story. You can do this easily because each section is clearly marked 1893 or 2009.
