In 1887, LeRoy is stuck, bringing trouble down on those around him. Sissy is kidnapped and he's the only one who can save her. Amaryllis wakes up in 2030, in a future very different to the one she knows, one in which she may not have been born. She will stop at nothing to find LeRoy fix what went wrong in the past. She and a version of Monique which is different from the one she grew up with travel back to 1887 to try and make things right.
Add two time travel regulators from the future who are after the time module, and things begin to get wild. When the time loops are crossed, things change, but not the way Amaryllis intended and pretty soon, everybody is seeing doubles.
