The Pharaoh Key is the fifth book in the Gideon Crew series. It is scheduled to be released on June 12, 2018 and will be the twenty-sixth full-length Preston-Child collaboration.
"Gideon Crew—brilliant scientist, master thief, intrepid adventurer—is shocked when his former employer, Eli Glinn, vanishes without a trace, and Glinn's high-tech lab Effective Engineering Solutions shuts down seemingly overnight.
Fresh off a diagnosis that gives him only months to live, Crew is contacted by one of his former coworkers at EES, Manuel Garza, who has a bead on one final treasure hinted at in EES's final case, the long-awaited translation of a centuries-old stone tablet of a previously undiscovered civilization: The Phaistos Disc.
What lies at the end of the trail will either save Gideon's life--or bring it to a sudden, shocking close. Crew once again faces incredible odds--but as Gideon has proved again and again, there's no such thing as too great a risk when you're living on borrowed time."-Publisher's synopsis
