Whirly World [EPUB ebook] 

Theme-park blogger Jason Green is dead and his spirit is stuck inside Whirly World, his favorite place to be. What should be a dream come true turns into an abstract nightmare as Jason confronts malevolent forces trapping him there. Desperate to escape, he has to befriend the other ten ghosts inhabiting this afterlife, from a disgruntled hostess crushed under a revolving stage, to a bereft security guard that still thinks it’s 1983, and combine their strange powers to dig up the park’s mysterious past.
