As an avid reader of historical fiction, I really enjoyed this book. Mr. Liss does a fine job of interweaving a murder mystery with a cultural identity "crisis." His exploration of the protagonist's submerged feelings about his father and his Jewish heritage is compelling and does not belabor the main mystery plot of the novel. His characters are well-developed and engaging. I can't wait to dig into "Coffee Trader." Many kudos from a sleep-deprived reader!
