Tether

Sasha returns to Aurora, the parallel universe of generals, princesses, body doubles, and the boy she loves, Thomas, where she tries to help and find missing people and save them all. Now that she knows parallel worlds are real, and than an alternate version of herself exists in a world called Aurora, Sasha's old life no longer seems to make sense...and her heart breaks daily for Thomas, the boy she left behind. Troubled by echoes of a self she was just beginning to discover, Sasha makes the difficult decision to journey once more through the tandem. Waiting on the other side is Selene, Sasha's analog from a third universe. They have a joint destiny - if Sasha is willing to turn her back on love.
