The Death Code — Lindsay Cummings

With short, fast-paced, alternating-point-of-view chapters, "The Death Code" starts several weeks after "The Murder Complex" ended. Zephyr keeps the secret about Meadow close -- that if she dies, The Murder Complex will be destroyed, too. Meadow, desperate to find her brother, father, and little sister, is determined to fight fearlessly to the end, even if it means sacrificing herself and her friends, new and old. "The Death Code" introduces a memorable cast of secondary characters and delivers a vivid and scary thrill-ride read.
