New Achievement! Total, Utter Failure. You failed a quest less than five minutes after you received it. Now that’s talent. A floating fortress occupied by warrior gnomes. A castle made of sand. A derelict submarine guarded by malfunctioning machines. A haunted crypt surrounded by lethal traps. It was supposed to be easy. One bubble. Four castles. Fifteen days. Capture each one, and the stairwell is unlocked. Here's the thing. It's never easy. Carl and his team can't go it alone. Not this time. They must rely on the help of the low-level, I-can't-believe-these-idiots-are-still-alive crawlers trapped in the bubble with them. But can they be trusted? Welcome, Crawler. Welcome to the fifth floor of the dungeon.

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.

Hell is empty and all the devils are here… Alex Stern made it to hell and back more than once, but this time she left the door open behind her. Demons are creeping through the streets of New Haven and the Yale campus, feeding on the souls of the living, terrifying the dead. Alex and her allies can hunt them, but it’s only a matter of time before the gates to the underworld open and they face a war they cannot win. To stop it, they’ll have to reach deep into the secrets of Yale and its societies, and discover the truth hidden in Alex’s own blood. While she struggles to hold onto the dream of a future Yale once offered, Alex must contend with the machinations of a corrupt Lethe Board and a deadly vampire with his own connection to the societies. But for the first time in her life, she won’t have to face the fight alone. Dawes, Turner, Mercy, and even Tripp will have a role to play, none more so than Alex’s mentor Darlington, the golden boy who lived so long in her head, now back in the flesh and cursed with dangerous powers of his own. Hell itself is stalking the delegates of Lethe House, and they’re all about to learn that demons don’t play by human rules.

"You’re not going to murder me in the night, are you?" Emily asks. "Haha. That’s funny," I say. Of course, I’m not going to murder her in the night. I need my laptop back first. That’s the whole point of making friends with Emily Harper, author of the hugely successful novel Diary of an Octopus . So I could get inside her apartment and take back what’s mine. Emily doesn’t know who I really am. She thinks I’m her biggest fan, her new best friend who happens to need a place to stay for a few days. She doesn’t realize the laptop she found—and took—from a busy airport almost two years ago was mine. I didn’t care about the laptop, just what was on it. My diary. The one I kept many years ago as a troubled thirteen-year-old girl with a vivid imagination and a flair for the dramatic. The diary Emily Harper has now published as her own. She thinks it's a story about a schoolgirl’s crush on her teacher, but she’s wrong. It’s a story about a murder. Two murders, if you count the hamster. She thought it was okay to make a few changes and publish it under her own name, but she was wrong about that, too. Because sometimes, truth is deadlier than fiction.
