Wave had always considered herself a good driver. Well, until she crashes into a desk. Now her hover car is junk, her eardrums are ruptured, and instead of admitting her for a thirty-second surgery to fix it, her insurance company just gives her a damn hearing aid.

When someone hacks into the hearing aid's operating system and speaks to her in the voice of the mysterious radio host Aki, Wave just wants to lock herself in her apartment and shut the whole world out. But then the news report that Aki has thrown himself to his death the day before, and Wave begins to investigate.
