1. Lincoln and the Border States: Preserving the Union by William C. Harris (UP of Kansas, 2011).
I'm happy that Kansas sent me a review copy of this one. The Civil War in the border states (esp. Missouri and Kentucky) is my primary interest and I've had my eye on Harris's book for a long time. There have been some good studies released recently, including a nice look at civil rights in Missouri, but Harris surveys in a single volume the military, social, and political challenges presented by all of them to the maintenance of the Union war effort.
2. The C.S.S. Albemarle and William Cushing: The Remarkable Confederate Ironclad and the Union Officer Who Sank It by Jim Stempel (McFarland, 2011).
Given the thin bibliography, I have my doubts that this book will add much to what's already been written about Cushing and the Albemarle, which is a great story if you're not familiar with it.
