Every teenager experiences obsessions, those little things that swirl around all day in your brain? For some it may be makeup tutorials, YouTubers, dancers, or even inspiring artists. But for Sheridan White it was the opposite: 4 Australian boys all in the band 5 Seconds of Summer. Like any fan girl she has posters, a lot, but what happens when a new poster turns out to be something different. Sheridan finds herself falling, literally, in the new poster and ending up in a strange world. Now she has to find out what is real and what isn't. Along the way experiencing amnesia, new friends, and blossoming feelings for the one and only Luke Hemmings. The real question is though is it all a dream?
