Two rock stars. One world tour. One line neither of them planned to cross. When Black Halo joins 5 Seconds of Summer’s Everyone’s a Star World Tour, Y/N expects sold-out arenas, sleepless nights and a lifetime of memories. She doesn’t expect Luke Hemmings. Between blazing stages, late-night conversations and months spent on the road, an unexpected friendship begins to blur into something neither of them can ignore. But falling for Luke means risking more than her heart—including the friendship of the man who’s loved her all along. Sometimes the person who changes your life is the one you never saw coming.
