I love the horror genre but rarely am I thrilled when I take a chance on an unknown (to me) author. IMHO, tone is the most important element of horror. I have no interest in farcical, surreal, ambiguous, over-the-top stories in which the true tonal qualities of horror (suspense, terror, shock, etc) take a back seat to humor or clever absurdities. I also dislike over-written "epics" in which you lose track of the multitude of supporting characters who pop up long after you've forgotten who they are, or grow sleepy reading repetitive descriptions or unimportant details whose only purpose is to pad out the length of the novel.
Darkness on the Ice is tightly written old school horror laced with action-adventure. The setting is highly atmospheric; Greenland in the winter months of WW2, a time before satellites, when communication technology was limited and remote arctic islands were isolated and inaccessible. Even more desolate than the setting of 30 Days of Night (which perhaps owes a serious debt to this novel?)
A lone vampire is planted by the Nazi high command at a key radar station. His vampiric nature is a secret; his mission is to protect the station from a squad of American GIs intent on finding and destroying it. His cruel temperament and mysterious ways create antipathy and suspicion among his fellow Germans, a mix of Nazis and regular career soldiers, but they assume he is just another over-zealous Nazi prick. The storyline is fairly rudimentary but the writing skills of the author keep it fresh and involving. Tilton is two cuts above most writers toiling in the genre.
If you're in the mood for a well-written, atmospheric horror adventure, Darkness on the Ice is a very solid choice. The only questionable thing about it is, with the popularity of the vampire genre and the success of John Carpenter's The Thing, how the hell did Hollywood miss out on this one?
