"Strange hallucinations have plagued PhD student Andie Robertson throughout her life. After years of consulting doctors, she decided the visions were a glitch in her own mind--until her mentor, the famous physicist Dr. James Corwin, is murdered in Italy, and Andie finds a stack of ink drawings in his office that bear a remarkable resemblance to her hallucinations. Shocked, Andie digs deeper and learns that Dr. Corwin developed a device that might shed light on the very nature of reality. She is even more stunned to discover that her mother, an academic who disappeared when Andie was a young girl, might also be involved. Determined to find answers, Andie follows a trail of clues placed by Dr. Corwin, for reasons unknown, in museums and cultural sites around the world, highlighting human achievement as well as a tapestry of secret knowledge woven into the threads of history. Yet Andie is not the only one searching. Powerful forces know of her mentor's invention, including a mysterious elite society that spans borders and will stop at nothing to find the device. Now a target herself, Andie and a disgraced journalist embark on a perilous journey that might hold the key to a new frontier of knowledge--and which also promises to unlock the doors of her past"--
