Meet Warren the 13th. He’s the lone bellhop, valet, groundskeeper, and errand boy of his
family’s ancient hotel. It’s a strange, shadowy mansion full of crooked corridors and mysterious
riddles—and it just might be home to a magical treasure known as the All-Seeing Eye. But if
Warren is going to find the hidden treasure, he’ll need to solve several other mysteries first:
What is the strange creature lurking in the hotel boiler room? Who is the ghostly girl creeping
around the garden’s hedge maze? And why is the hotel’s only guest covered in bandages? Full
of puzzles, secret codes, outrageous inventions, and hundreds of intricate illustrations, Warren
the 13th and the All-Seeing Eye will delight and confound readers of all ages.
