Gr 3-6 –Although he’s only 12 years old, Warren the 13th is the sole heir to his family’s once magnificent hotel. Unfortunately, the hotel has fallen on hard times since the death of Warren’s father five years earlier and since Warren’s Uncle Rupert brought his bride, Aunt Annaconda, to stay. Annaconda is bent on finding the hotel’s legendary hidden treasure, the All-Seeing Eye. When a mysterious bandaged guest checks in to the hotel, Annaconda is convinced the guest will locate the Eye before she does, and a breakneck treasure hunt ensues. Warren is swept up in the action, hoping to discover his rightful inheritance before anyone else does. Along the way, he must outsmart witches and monsters and puzzle out the answers to riddles, secret codes, and mazes. Kevin T. Collins expertly narrates this story, distinctly voicing each character and adding just the right sinister overtones to Annaconda and her evil sisters. Creepy instrumental music at the beginning and end of each disc also enhances the production’s melancholy vibe. VERDICT Listeners will immediately be pulled in to this spine-tingling mystery and will eagerly join Warren on his hunt for the All-Seeing Eye. [“A whimsical mystery with a lot of heart and spine-tingling illustrations, this novel will circulate as soon as children open it”: SLJ 1/16 starred review of the Quirk book.]–Anne Bozievich, Friendship Elementary School, Glen Rock, PA
