I generally read histories, biographies, and police procedurals. However, last year a read Walsh's "The Raven Gang" (a mystery/sci-fi/fantasy) and enjoyed it. I recently read Walsh's latest, "Immortale" which is more of a sci-fi, I enjoyed it immensely. I loved the main character "Pierce". The plot was unique and the characters were well-drawn. I can't wait for his third entry.
