In the midst of a giant forest live the people of Zurec, a skittish clan whose traditions consist of avoiding bloodthirsty monsters and hiding in a hole. Headstrong fifteen-year-old Lillian Zurec can't wait to ditch their burrow, join Zurec's elite warriors, and see the world. Meanwhile, her timid best friend Mary is content to stay underground, safeguarding her dying clan's few children as the next caretaker. Survival on a planet where humans are near the bottom of the food chain is hard enough, but at least among the thousand-foot trees of the Giant Wilds, Zurec is protected from them. Or... that's what they thought.

When their next-door neighbors are killed by a forty-foot-tall species of intelligent giants, these two young women must question Zurec's very way of life. Their clan is dying and everything they care for could be destroyed. The capaemen rule this world, and they always win. But why now?

Why are the capaemen attacking after all this time?

The two girls seek to answer that question: one in their own backyard, the other in places beyond her wildest dreams. Through bravery and strife, they uncover secrets that could overturn everything they thought they knew about power, accountability, and good versus evil. So tiny and powerless in this world of giants, can either of these girls save their people?

They may be small, but even the small can make huge ripples.
