Chris Bohjalian

I really like Bohjalian's writing style. He has written more books if you liked this one. I have read Midwives and Double Bind which are both by Bohjalian. I may try another one or two as well.

Here are some other suggestions to read if you liked The Buffalo Soldier. I found this list of suggestions at this site.
Russell Banks, The Sweet Hereafter; Judith Guest, Ordinary People; Jane Hamilton, A Map of the World; Sue Miller, Family Pictures; Alice Sebold, The Lovely Bones; Anita Shreve, Sea Glass; Susan Straight, Highwire Moon.

I personally do not plan on reading The Lovely Bones because it looks too scary for me!

You can learn more about Christ Bohjalian at his website. It looks interesting.
