For three years, Leuh Yarm has fought in the endless war against the horrors of the Maw. For three years, she has suffered and endured the rigours of battle, finding purpose in the struggle while trying to forget the past that brought her to the island.

Then a new commander arrives, claiming his intention to end the war. Leuh dismisses him as a mad man. After all, this is a war that never ends.

But everything changes when the creatures of the Maw begin attacking with greater ferocity. As the nightly battles turn to slaughters, Leuh finds herself faced with an impossible choice: to either accept annihilation or else embrace the commander's mad plan to end the war...

By entering the Maw itself.
