Quick Facts

Short Summary

After her mother Jo’s death, twenty‑four‑year‑old Bridge discovers a strange cocoon called the dreamworm in the freezer. As a child, Jo had used the worm to travel into alternate realities, and Bridge begins to believe her mother might still be alive in another dimension. With the help of her skeptical friend Dom and a musician named Caden, Bridge learns to swap consciousness with her other selves. But her visits scatter dreamworm eggs across realities, attracting the attention of a ruthless hunter, Amber, who leads a hive‑mind collective determined to eradicate the infection. Bridge’s search forces her to confront the damage she causes, the truth about Jo’s betrayal, and the parasitic price of multiverse travel. Ultimately she must choose between saving her mother and protecting the many versions of herself.

Full Summary

The novel opens in April 2006, when seven‑year‑old Bridge accompanies her mother Jo on a tense road trip to New Orleans. Jo, a neuroscientist obsessed with a device called the dreamworm, visits a woman named Mina and acquires a shriveled cocoon. Bridge remembers little of these events until, seventeen years later, she and her friend Dom begin cleaning Jo’s ransacked house in Portland. In the freezer, Dom finds a container holding the dreamworm—a lumpen, yarn‑like object. On impulse, Bridge breaks off a strand and swallows it. She later breaks a second piece and uses a video of a zoetrope and sitar music to trigger a vivid experience; she wakes convinced she has visited another reality.

With Dom’s reluctant support, Bridge contacts Caden Lyall, a musician who worked with Jo. Caden explains that the dreamworm is a consciousness conduit that allows a person to swap places with their alternate self in a compatible universe. Bridge begins a series of brief jumps, cataloging the lives of her other selves—most of whom are dead from brain cancer, accidents, or violence. In one of these jumps, she speaks on the phone with a version of Jo who is alive. This fuels her determination to find her mother, even as Dom grows increasingly worried about the cost.

Meanwhile, Amber, a former soldier and police officer, leads the Ourmind, a hive‑mind collective of her own alternate selves. They hunt down people infected by the dreamworm, using a device called the Hellshriek Box (or Frequency Machine) to extract the parasitic threads. Amber identifies Bridge as a source of an infestation and begins tracking her across realities. She lures and kills an infected man named Aiden, then sets her sights on Bridge.

Bridge’s jumps become more urgent. She tries a “blitz” method, cable‑tying herself to Caden’s bed and making dozens of five‑minute visits, each time asking about Jo. The experience leaves her disoriented and grieving, as she learns that most of her other selves are already dead. Dom creates a spreadsheet of 67 realities: 46 dead, 9 promising, only 2 confirmed alive. Bridge refuses to stop.

During one jump, Bridge arrives in the body of Budgie, a mother of two who is fleeing her abusive ex‑partner, Franco. Budgie has been experiencing dissociative episodes—Bridge’s consciousness taking over. Amber captures Budgie and tortures her with the Frequency Machine, but Franco bursts in and fights Amber off. Bridge escapes and manipulates Franco into driving her to Jo’s house. She eventually reaches a cabin in the Rockies where Jo is hiding. The reunion is emotional, but Jo soon confesses that she deliberately swapped lives with Budgie without consent. Jo explains that Rabbit, the cocoon’s creator, taught her to use a box that can permanently overwrite a host. Jo is immune to extruding (the process that leaves dreamworm eggs) because of her epilepsy, but the switching still harms others.

While Bridge and Jo try to decide what to do, Dom ingests the dreamworm and jumps to Puerto Rico to warn Bridge. Dom reveals that Caden is dead, Tendayi is wounded, and Budgie killed Amberlynn (one of Amber’s selves) in self‑defense. Bridge and Jo find a seizure‑frequency video that can kill the worm without harming the host. They test it on Amber, disabling the hive mind and disconnecting the other Ambers. Bridge refuses to stay in Jo’s reality, acknowledging that Jo is dead in her own world and that she must return to help the other Bridgets.

Two months later, Bridge is in a psychiatric facility, recovering. Dom visits and brings gummy worms laced with dreamworm fragments. Bridge plans to use them to dream other lives and warn alternate selves. She promises Dom she will always return.

In a postscript diary entry, Joanne (the version of Jo in Budgie’s reality) discovers Budgie wounded after killing someone in another reality. Joanne secretly removes a dreamworm from Budgie’s arm and decides to use the worm to travel to a successful version of herself, burning the journal to hide her plan.

The book ends with a promotional section encouraging readers to explore more content.
