"In the final book in the Twinmaker series, Clair, Q, and Kari Sargent must enter The Yard, a digital landscape created by their enemy, in order to save the world"--

Clair and Jesse have barely been reunited when the world is plunged into its biggest crisis since the Water Wars. The d-mat network is broken. The world has ground to a halt. People are trapped, injured, dying. It's the end of the world as Clair knows it -- and it's partly her fault. Now she's been enlisted to track down her friend Q, the rogue AI who repeatedly saved her life -- and who is the key to fixing the system. Targeted by dupes, abandoned...

Odo is the seventh son of the village miller and he just wants to get away from work for awhile, Eleanor's mother was a soldier, and she yearns for adventure, but it is Odo who finds the magic talking sword named Biter, and thereby instantly becomes a knight--and together they set out on a quest (somewhat reluctantly on Odo's part) to save their kingdom from threats both human and dragon.

When their house mysteriously explodes and they are sent to live with an unknown relative named Grandma X, twelve-year-old twins Jaide and Jack Shield learn that they are troubletwisters, young Wardens just coming into their powers, who must protect humanity from The Evil trying to break into Earth's dimension.

When the old man who lives in Rourke Castle dies mysteriously, troubletwister twins Jack and Jaide Shield find themselves drawn into a search for something hidden in the castle--something that The Evil wants desperately--but they have no idea what it is they seek.

The Wardens have devised a plan to get rid of The Evil once and for all, and troubletwister twins Jack and Jaide, and Grandma X, are at the heart of the scheme--but even if it works a lot of innocent people may die or end up abandoned in the dimension of Evil.
