Morton (The Forgotten Garden) has quickly established herself as a master of modern gothic, producing complicated and completely satisfying historical mysteries. Her third novel solidifies her dominion. As a wartime evacuee from London at the time of the Blitz, 13-year-old Meredith Baker is in awe both of the ancient Milderhurst castle where she is staying and of its inhabitants, the Blythes—sweet and maternal Saffy; her shrewd twin, Percy; and the wild and talented Juniper, who becomes Meredith's best friend. Fifty years later, a lost letter arrives to remind Meredith of her time at Milderhurst, even though she has long tried to bury the memory. It falls to her daughter, Edie, to begin to untangle her mother's secrets. The trail leads back to Milderhurst and the Blythes and into an even thicker nest of hidden mysteries that Edie is determined to uncover. VERDICT Featuring a fresh and thrilling gothic mystery, cinematic storytelling, and fully developed characters who possess layers of deliciously surprising secrets, this complex story is developed at a leisurely but compelling pace that keeps readers hooked. Recommended for a wide readership, including mystery lovers and historical fiction fans. [See Prepub Alert, LJ 6/15/10.]—Therese Oneill, Monmouth, OR
