In style, tone and some substance, this book feels very similar to Stephen King's The Stand. That's a compliment! There are massive differences, not least that Last Call is set in a world which hasn't quite gone post-apocalyptic but if you enjoyed The Stand then you should shuffle this one to the top of your reading list.
Last Call is an intricate, well plotted, slightly baffling supernatural mix of myth and modernism, set in Las Vegas at a pivotal time. The Old King needs to take a new set of bodies to survive and all the action happens through card games. His son is one of his targets, but his son could also be the only real threat to the Old King's supremacy. The resulting battle is played out in casinos and bars, while the hero's life disintegrates around him as the dark lords of drink and death tug at his coat-tails.
If you enjoy Neil Gaiman's Sandman stories of gods walking in the modern world, or enjoy the idea that all the characters are avatars from a deck of cards, or are captivated by the idea that the tarot may be true, then this book will grab you from the get-go. The characters are compelling and it's very well written. I didn't understand all of the references or most of the poker play, which made some segments of it hard to understand but that didn't detract too much overall.
Some scenes are genuinely chilling, and some of the characters utterly repugnant. Like many 'quest' novels there is a fair bit of running around in circles but it builds to a very satisfying resolution. And you never quite know who is going to make it to the end of the final chapter in one piece...
