Picking up where Chris Owen's Converge left off, Finn has crossed into Ari's dimension, but now what? He's a man without a past, without papers, and he can't get home. Now that he and Ari are together in body as well as spirit, they can move their relationship forward. But the uncertainty of Finn's status, and Finn's unfamiliarity with Ari's dimension, are definitely standing in their way.

On top of that, something strange is going on. People in Ari's dimension are not only disappearing, they're reappearing again days later. Tracking the news and combining it with the information he has about dimensions and Between, Finn begins to suspect that his appearance in Alpha and these strange happenings are connected for sure.

As he and Ari work together to help Finn adjust to Ari's life, their quest for a way to restore communication with Alpha begins. Through some clues from Alpha, and an unexpected revelation about Finn's friend Blake, Finn and Ari find someone who might be able to help him. But is the potential cost to them -- and to Finn's friends and family back in Alpha -- worth the attempt?
