" "Lincoln Letter" is told through simultaneous action in both the Civil War and modern eras. Unfortunately, the modern characters and setting cannot keep pace with those events and personalities surrounding the Lincoln White House. Much of the historical representation is interesting, and some characters have interesting color and interwoven back stories, but the action is less than breakneck and modern characters are more often disappointing caricatures. For any true fan of historical thrillers, there are several more viable options. This one, while not entirely unworthy, is better left to simmer on the back burner. "
