Creek of Bones in Bloomington, MN

Kev MacGuire is dying. Crabbing comforts him, and one day he catches human bones and a strange, gold medallion. When it turns out to be Incan, Kev and friends investigate how jewelry once stolen by conquistadors ended up near the Chesapeake.
If tales found on an old plantation are true, Blackbeard and his pirates looted treasure from a wrecked Spanish galleon. Along with liquid drawn from the Fountain of Youth.
Kev and friends search for the valuables but dismiss the Fountain as fantasy. But when a centuries old cure makes him a believer, the lighthearted quest becomes a race for survival.
