An obscure trilogy in the Forgotten Realms universe, the Twilight Giants books focus on a little-known kingdom in the far, frozen north populated by humans, giants, and their kin. In this, the first entry, Princess Brianna is kidnapped by ogres and her suitor, Tavis, sets out to rescue her.
"The Ogre's Pact" is essentially one long chase, but Troy Denning keeps things interesting with a wide variety of unexpectedly grotesque obstacles. Avalanches, rock slides, animated severed heads, cannibalistic ogres, undead mountain lions, debauched hill giants... the heroes rarely have a chance to rest. And unlike most books in the genre, the protagonists take an incredible beating. You're never really sure who might live to see the final page. Denning does an excellent job of reminding us just how cold the setting is - the freezing temperatures almost become the primary antagonist.
While the action and tension are both handled well, characterization isn't very strong. Most of the supporting cast is interchangeable (they're the kind of characters with no real "voice" of their own), and even the main characters are fairly one-note (Tavis is honest, Brianna is feisty, Basil is greedy, etc). One notable exception is the ogre shaman, Goboka, but he gets very little face-time and is usually relegated to being a background menace.
Fantasy devotees will enjoy the insights into giant culture that this book, and the others in the series, provide. With no stock characters like elves, dwarves, goblins, or orcs cropping up, "The Ogre's Pact" provides a fresh variety of characters and monsters in a fascinating setting. It's a quick read that is well worth the time.
