This is a terrific novella and it's only $2.99! Woot! What an excellent addition to the Iron Druid Chronicles. Some of Atticus's decisions from prior books are coming back to haunt him and the decisions he makes in Two Ravens and One Crow will have ramifications in later on.
I missed Oberon, Atticus's meat-lovin' Irish wolfhound!!! Atticus and Oberon's back and forth always has me in stiches and while we get a little bit of that interaction, Atticus has to leave Oberon behind on this trip. However, we do learn more about the Morrigan and how Atticus comes to learn how to make Immortali-Tea (think he'll share that recipe?).
I loved the quick pace, action and wit that comprised the story. If you're like me and counting the days until Trapped (Iron Druid #5) comes out in November 2012, then pick up Two Ravens and One Crow. It will help tide you over and make the wait a little more bearable.
