"The training levels have concluded. Now the games may truly begin." The ratings and views are off the chart. The fans just can't get enough. The dungeon gets more dangerous each day. But in a grinder designed to chew up and spit out crawlers by the millions, Carl and Princess Donut need to work harder than ever just to survive. They call it the Over City. A sprawling, once-thriving metropolis devastated by a mysterious calamity. But these streets are far from abandoned. An undead circus trawls the ruins. Murdered prostitutes rain from the sky. An ancient spell is finally ready to reveal its dark purpose. Carl still has no pants. They call it Dungeon Crawler World. For Carl and Donut, it's anything but a game.

Welcome to the Gun Show! The top ten list is populated. The sponsorship program is open. The difficulty is ramping up. The first three floors were nothing compared to what Carl and Donut now face. The Iron Tangle. An impossibly-complicated subway system built out of the world's subterranean railway systems, all combined and then tied together into a knot. Up is down. Down is up. Close is far. The cars are filled with monsters, the railway stations are less than safe, and the exit is always just a few stops away. But there is hope. For the first time, the crawlers are all working together. The loot is better than ever. And the secret to unraveling it all may be hidden in the pages of a seemingly-useless book. Welcome, crawlers. Welcome to the fourth floor of the dungeon.

Celaena Sardothien is her kingdom’s most feared assassin. Though she works for the powerful and ruthless Assassin’s Guild, Celaena yields to no one and trusts only her fellow killer for hire, Sam. When Celaena's scheming master, Arobynn Hamel, dispatches her on missions that take her from remote islands to hostile deserts, she finds herself acting independently of his wishes—and questioning her own allegiance. Along the way, she makes friends and enemies alike, and discovers that she feels far more for Sam than just friendship. But by defying Arobynn’s orders, Celaena risks unimaginable punishment, and with Sam by her side, he is in danger, too. They will have to risk it all if they hope to escape Arobynn’s clutches—and if they fail, they’ll lose not just a chance at freedom, but their lives . . . A prequel to Throne of Glass, this collection of five novellas offers readers a deeper look into the history of this cunning assassin and her enthralling—and deadly—world. Included in this volume: The Assassin and the Pirate Lord The Assassin and the Healer The Assassin and the Desert The Assassin and the Underworld The Assassin and the Empire
