When her growing talent captures the attention of Nicholas Montague, a brutal criminal who traffics in human beings, Molly flees. Her escape is unexpectedly aided by a mysterious figure who communicates from the shadows in soft hisses whisper. This person promises to protect Molly from Montague-in exchange for one small favor: Molly must break into the only unbreakable mind in London, Sir Edward Carlton, lockbox for Her Majesty's Government. Desperate to escape Montague, Molly agrees. She gains entry to Sir Edward's house, mind, and friendship. Sneaking into his thoughts each night, Molly finds tantalizing clues about a tragic love that haunts Sir Edward. She also uncovers information about a powerful secret society. Soon Molly finds herself enmeshed in a tangled web, unable to tell allies from enemies who blackmail, kidnap, and murder with ease. Unwilling to have her powers used for evil ends, Molly tries to escape. But her employer refuses to allow that. Sir Edward is snared in a vicious trap, and Montague captures Molly's best friends from the street. Alone, she must choose between her life and theirs-or use her wits and growing power to change the rules of a game she doesn't understand.
