Charlie, Kippy, Adrian and Ricky are once again visiting Engris and decide to visit their friendly ghosts Billy and Will in the spirit domes. However, the domes created by the Madracorn that have worked perfectly for many millions of years have a big problem. They are clogged up. The Madracorn ask Charlie for help, and he quickly realizes this is a job for Third Planet Inquiries.
As with all Geron's stories, this is filled with humor, mystery and adventures. It is also darker than his usual Charlie Boone stories which is fitting since Charlie and his team are adults now. The job has many dangers, a great cast of old and new characters and some excellent cliffhangers. As for the setting? World building in this story is a universal understatement! Enjoy the read!
