The Train to Impossible Places 02: The Great Brain Robbery

Suzy Smith and her friends have gathered again for the re-launch of The Impossible Postal Express. The celebrations don't last long though before Trollville is rocked by a violent tremor—one of a series growing more powerful by the day.
It's clear something sinister is underfoot. Nevertheless, Suzy's got a long-overdue package that the Express must deliver, and it may just lead her to some answers.
Suzy and the Express will travel deep under Trollville through the Uncanny Valley, and sky-high to new impossible places like Cloud Forge. She and the gang will test out its kinks, new features, and meet new allies and enemies alike, from a sentient cloud-consciousness to an obnoxious magician.
