A middle-grade fantasy and nonstop adventure, The Train to Impossible Places by debut author P. G. Bell is as fun as it is full of heart and the first audiobook of a planned trilogy. A train that travels through impossible places. A boy trapped in a snow globe. And a girl who is about to go on the adventure of a lifetime. The Impossible Postal Express is no ordinary train. It's a troll-operated delivery service that runs everywhere from ocean-bottom shipwrecks to Trollville and to space. But when this impossible train comes roaring through Suzy's living room, her world turns upside down. After sneaking on board, Suzy suddenly finds herself deputy post master aboard the train and faced with her first delivery - to the evil Lady Crepuscula. Then, the package itself begs Suzy not to deliver him. A talking snow globe, Frederick has information Crepuscula could use to take over the entire Union of Impossible Places. But when protecting Frederick means putting her friends in danger, Suzy has to make a difficult choice - with the fate of the entire Union at stake.

The adventure continues in book two of the stunning The Train to Impossible Places middle-grade fantasy series! 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. In this second book in the Train to Impossible Places trilogy, 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, er, new features, and meet new allies and enemies alike, from a sentient cloud-consciousness to an obnoxious magician.
