I was surprised by how much I liked this as I was expecting a knockoff of Jaws, but this is a very different beast to be sure. Killer begins at a military base in Oregon where they train animals like porpoises to attack and guard ships and such. Their real prize is a huge orca that they have trained to go after human beings since it was little. Now, the beast is huge and when the brass come to inspect it (funding you know?) an accident happens and the orca flees.
Tonkin switches gears after introducing the monster (although he often switches POVs back to it when things get interesting!) and presents the rest of the cast of the tale. Kate, a post-grad research fellow, is off to Alaska to join and expedition there, one lead by her father, a renowned scientist. He greats her at the airport, along with the rest of the crew, and off they go, flying to bring in new supplies to the old camp. Well, the plane crashes on the pack ice North of Barrow, Alaska, and the team-- a handful of people-- are stranded on an iceberg. If that was not bad enough, our 'friendly' killer whale, now with a few dozen followers, find them and figures out it is time for some tasty human meat...
While obviously Killer concerns a classic 'man versus beast' narrative/plot, what makes this one stand out involves the climate. The Artic is frigging cold, even in summer, and this becomes the big enemy off the bat. Made me shiver just thinking about it! Among the handful of stranded explorers/scientists, several are experienced 'cold men' and know how to survive, and, luckily, the plane was bringing in new supplies, so they have tents, food, etc., and just hope for a quick rescue. Their struggles with the cold, a polar bear, a pack of walruses, and yes, the orca and his buddies altogether make this adventure tale/thriller/horror novel shine.
There are some issues with the characters, giving this a dated feel. Our (almost) token Eskimo with his native lore screams bad stereotype; Kate goes from being a rock to a damsel in distress at the drop of a hat; her father the scientist is also a bad stereotype, etc. Yet, if you can get by these flaws, Killer proves to be a fun and gripping read. Pretty amazing given that this was Tonkin's first novel. 4 toothy stars!!
