In this exciting conclusion to BETWEEN...A young boy vanishes into the Alaskan wilderness.It's a harsh land, and his disappearance barely stirs national interest. But strange signals detected by a nearby observatory raise alarm bells for theoretical physicist Anne Fleming-and send her running to Carpes.She needs help.She needs the one person who will never trust her.She needs Marda.Joined by Ben, Marda follows a trail that stretches from Carpes to Africa and then to Alaska. There, they discover a vest made from the same alien material as Marda's glove.This is no longer a missing person's case.It's a search for a new portal.A new Stellar Bridge.But Carpes has been scanned. There are no other bridges. So where does the Alaskan portal lead?And who-or what-will they find waiting on the other side?
