This Inevitable Ruin (Dungeon Crawler Carl) by Matt Dinniman

from $15.60
Hardcover:

Book 7 of 8

The ninth floor changes everything—nine armies, one castle, and for the first time, death that doesn't come with a respawn.

#1 New York Times bestselling author Brandon Sanderson calls the series "legit awesome," and USA Today says it's "highly addictive" and still winning new fans with every book.

In the seventh installment of the Dungeon Crawler Carl series, Carl and Princess Donut are thrown into Faction Wars, a brutal free-for-all where nine armies scramble to seize a central castle. For once, the danger isn't only the dungeon's monsters—it's the other players.

In a shocking twist, the game's NPCs have become self-aware and banded together as their own faction, upending the rules Carl and Donut thought they understood. And unlike previous levels, death on this battlefield is permanent—for everyone.

As the stakes reach a terrifying new high, only one of Donut or her rival Katia will make it off this level alive, forcing Carl into some of the hardest choices of the series so far.

Packed with the dark humor, ferocious action, and unexpected heart that made this series a phenomenon, This Inevitable Ruin raises the bar yet again.
