Unseen Forces - Sky Wilder, #1

Maverick archeologist Dr. Sky Wilder has never been able to prove any of his outside-the-box fringe theories... until now. When he breaks what had been an impenetrable code, he unearths a long-buried Egyptian stone tablet in Arizona's Red Rock country. Whoever possesses all three hidden tablets holds the key to locate an ancient alchemical text containing a formula for physical immortality. The bodies pile up as Wilder realizes he's been set-up as a pawn, caught between opposing covert agencies and secret brotherhoods that have been warring for centuries.
