Reviews

“An engaging mystery to unravel, with a few nice twists and surprises along the way. . . . It’s a fair bet that for many the main attraction of Warren the 13th and the All-Seeing Eye will be Staehle’s lavish illustrations.”—New York Times Book Review

“A whimsical mystery with a lot of heart and spine-tingling illustrations, this novel will circulate as soon as children open it.”—School Library Journal, Starred Review
