I’m a fan of Preston and Child’s Pendergast series. Have also read some of their trilogy series and many of their stand-alone books. “The Lost City of the Monkey God” was one of them. Quite a while ago, Amazon had a special on it in Kindle format so I took the plunge. Besides skin eating parasites, they had to be extremely careful of the Fer de Lance snake, a highly venomous pit viper species.
Sounds like a great place for a resort. /jk
