A Friend in Need is a short story collaboration between three different YA authors who combine their talents to create an intersection in an apocalyptic world populated with characters from their respective novels. LX and Jane (from Lynam's Time Will Tell series) time-crash into Tim Hemlin's The Wastelanders. Their only hope of returning to their own world requires help from Bear, Caballito, and the time-witch. Enter Calla and Valcas, (time-travelers from Chess Desalls' Call to Search Everywhen series,) who land in the wastelands while conducting a time-search of their own. Will the travelers be able to return, or are they stuck in the wastelands forever?
