This book (volume 3, which collects #18-26) picks up the tale right where the last issue in "Untill the end of the World" left us, with Jesse going on his way to rescue Cassidy from the Grail. Before the actual rescue operation begins we first get a little intermission-window-tale (#18) where Jesse meets a man at the airport who tells him a story about the time when he used to know Jesse's father in Vietnam. Not really an important factor for the rest of the story, but plenty entertaining. After that (#19-24) the search for Cassidy is on and you get to read a tale that makes the intentions of both the Grail as Starr a lot clearer (which was indeed a little neccesary). Starr however is expecting Jesse and waiting to ambush him, and the Saint of Killers is also on his trail again. Starr himself isn't having an easy time either since the allfather of the Grail comes checking up on him, a sign he thinks that they suspect something about his little scheme. With that we get to meet "the greatest treasure of the Grail" (who isn't exactly how you expect him to, to say the least) and Jesse meets a creature who learns him more about the Genesis entity. This is really a very good part of the story and, I dare say, the most important part of the TPB for those who are following the main story. Off course it's also filled with humorous little sub-plots you would never have thought of yourself in a million years, like we're growing used to from Ennis it seems. Finally the last part of the book (#25,26) handles the origin of Cassidy. It shows how and when exactly Cassidy became what he is now, how he learned to live with it, and how come he's in America now (being an Irish bloke). This little part falls a bit out of line in the Preacher saga sometimes (makes you think of Heartland, for those who've read it) when Garth makes clear how he feels about Ireland.
Like I said, a lot more about the Grail and their goals becomes clear now which really comes to the good of the series. It gets really clear what each player is in it for and what they hope to achieve. The bizar humor stays at the good level it's been for a while now, keeping the series a laugh-riot along the way of the great story. Dillons art is as good as before, clear and expressive without taking the attention of the story too much. A worthy successor after "Gone to Texas" and "Untill the end of the World"
