Fifteen years after a tragic accident shut down OceanView Adventures, Ethan begins receiving strange letters from the abandoned theme park. The messages are cryptic, the paper always damp, and the enclosed photographs show memories he doesn’t remember living. Desperate for answers, he sneaks inside—only to find the park isn’t as empty as it seems. The rides still hum, the water still rises, and the park’s beloved mascot, Guppy the Wonderfish, is waiting for him. But as the past unravels, Ethan realizes that some places never let you leave. Some things never stop swimming. And Guppy never, ever forgets.
