Some of Masterton's best books have been his series. My favorite is the Harry Erskine books, where Masterton works out his best uber Horror in the supernatural vein. Nathan Underhill has been introduced before, but the book is self explanatory even without a knowledge of his previous work.
This book brings together three streams of story that are not so far removed, but it takes a little bit of development before things take off ( in an almost literal sense). Underhill works on his project that can help with burns , but part of the way into the story he meets the son of his previous nemesis, and the main plot fires up ( as it were). The three threads intertwine in a brilliant way, and it is hard not to say much without saying anything about the key point. Suffice to say that this book has some classic Masterton moments ( not as extreme as THE HOUSE THAT JACK BUILT, but more like some elements, for example, in PARIAH). Fans of classic Masterton will, in my view, enjoy petrified, since it elicits the best of his mythic skills, and brings out more of his capabilities as shown in TRAUMA, aka BONNIE WINTER.
I will reveal that, I hope very much that this is the second of many books with Underhill. Masterton has a great formula here, and I hope very much that he brings out more of the style he created in PARIAH to combine with Underhill's special tone.
