Del's older sister can also walk between worlds, but her loyalties are uniquely tested in this original enovella set in the inventive world of Dissonance.

Addison Sullivan, Del's older sister, has always been considered a model Walker-but her reputation within the Consort has been tainted by her grandfather's betrayal and her sister's recklessness. She is desperate to regain her position within the Consort and equally desperate to keep Del from spiraling out of control after losing the boy she loves.

The Consort offers Addie a chance to redeem herself: if she can track down the Free Walkers her grandfather knew twenty years ago, they'll fast-track her apprenticeship and put her in charge of her own team. Addie asks a former classmate and crush, Laurel, a Consort historian, for help. As they work together, Addie's feelings for Laurel resurface, but she's too afraid to act. Same-sex relationships aren't expressly forbidden by the Consort, but she fears that a relationship with Laurel would be viewed as yet another mark against her.

While she is fighting her feelings for Laurel, troubling details start emerging during their investigation...details that paint Addie's family in a sinister light. Will she reveal what she's learned to the Consort, or try to protect her family?

This enovella is set in the time between Dissonance and Resonance.

Dissonance

Published 22 July 2014
Delancey Sullivan knows for sure that there is more than one universe. Many more. Because every time someone makes a choice, a new, parallel world spins off the existing one. Eating breakfast or skipping it, turning left instead of right, sneaking out instead of staying in bed - all of these choices create an alternate universe in which an echo self takes the road not travelled. Del knows all of this because she's a Walker, someone who can navigate between the worlds, and whose job is to keep the dimensions in harmony.

But Del's decisions have consequences too. And when she secretly starts to investigate other dissonant worlds she's intrigued by the echo versions of Simon Lane, a guy who won't give her the time of day in the main world, but whose alternate selves are uniquely interested. But falling for Simon draws Del closer to a truth that the Council of Walkers is trying to hide - a secret that threatens the fate of the entire multiverse.

As a Walker between worlds, Del is responsible for the love of her life—and the fate of millions—in this thrilling sequel to Dissonance. As School Library Journal raves, “O’Rourke brilliantly builds an intricate and complex alternate science-fiction universe…fans will be longing for the next installment.”

Del risked everything to save Simon, and now he’s gone, off in another world with no way for Del to find him.

She’s back at the Consort—training to be a Walker like everyone in her family. But the Free Walkers have other plans for her. This rebel group is trying to convince Del that the Consort is evil, and that her parents are unwittingly helping the Consort kill millions of people. The Free Walkers make Del the ultimate promise: if Del joins their fight, she will be reunited with Simon.

In agreeing, Del might be endangering her family. But if she doesn’t, innocent people will die, and Simon will be lost to her forever. The fate of the multiverse depends on her choice...
