#1 -- Megan Anderson is an out of work cyber crime investigative reporter. She decides to take a job as a guide in historic Boston, but as she conducts tours along the Charles River, a Revolutionary War era ghost makes her presence known and threatens Megan's peace of mind.
#2 Megan returns to the cyber field when Cal Garrett, a Boston police detective, pulls her into a murder investigation involving an internet treasure hunting game. She doesn't anticipate that her childhood crush, now a devastatingly handsome law man, will awaken a passion neither of them wants to ignore.
#3 -- Megan has always been the best friend of Cal's sister, but when she returns to Boston all grown up, his feelings dramatically change from brotherly friendship to something highly combustible. However, her belief in ghosts and Cal's belief in scientific police work will put them at odds. When Cal allows Megan to enter the game to help solve a crime, he puts her in danger and only solving the riddle of the game will save her. That, and suspending his disbelief to ask a ghost for help.
