The Giant Among Us

The Giant Amoung Us by Troy Denning is book two in The Twilight Giants trilogy.

"The rise of a new queen has shattered the ancient peace of the Ice Spires, and the only thing left standing between Hartsvale and the giant tribes bent on her destruction is a lone scout armed with a single golden arrow.

And now that sanctuary is about to end.

The queen is trapped in a remote citadel, surrounded by giants, and the scout who would save her must now leave her and undertake a harrowing journey to summon help. Only, as the scout soon learns, the greatest danger to the queen is posed not from without, but from within."
