“Combining a 1920s New York setting with ancient Turkish and Arabian folklore and history, this novel reads like a young Indiana Jones adventure. . . . As smart as it is action-packed.” —The Bulletin of the Center for Children’s Books   On a stormy May day in 1929, William and Maxine arrive on the doorstep of Battersea Manor to spend the summer with a grandfather they barely remember. Whatever the cousins expected, Colonel Battersea isn’t it. Soon after they settle in, Grandpa receives a cryptic telegram and promptly whisks the cousins off to New York City to meet an unknown courier and collect a very important package. Before he can do so, however, Grandpa vanishes without a trace. When the cousins stumble upon Nura, a tenacious girl from Turkey, she promises to help them track down the parcel and rescue Colonel Battersea. But with cold-blooded gangsters and a secret society of assassins all clamoring for the mysterious object, the children soon find themselves in a desperate struggle just to escape the city’s dark streets alive. “A youthful mystery worthy of John Bellairs, with lyrical language reminiscent of Edith Nesbit; yet it stands on its own, creating a fully realized world with clearly defined lines of good and evil, and just a dash of magic.” —Booklist “Readers of R. L. LaFevers’s Theodosia Throckmorton series as well as lovers of the Rick Riordan books will enjoy this. A well-crafted adventure with a dash of magic.” —School Library Journal  “Brumbach’s vivid descriptions and terse, to-the-point dialogue keep the action moving and readers constantly engaged and surprised. . . . A fast-paced, action-packed adventure.” —Kirkus Reviews Read Less
