Benjamin Forrest and the Lost City of the Ghouls - Endinfinium, #3

At the end of everything ... there is a new beginning. Benjamin Forrest and his friends witness their first triangulation, a ceremony for Endinfinium High's graduating pupils, where they can choose whether to remain with the school or make their own way in the world. Three brave pupils opt for adventure, but when, a few weeks later, one is found wandering in the Haunted Forrest, pursued by dangerous ghouls and babbling about a lost city, Benjamin and his friends are thrown into their most dangerous situation yet.
For the Lost City of the Ghouls is coming ... and it will stop at nothing to destroy Endinfinium High once and for all.
