Thanks to recommendations here I've now finished Fever Beach, Carl Hiaasen's latest, and it is pretty good, and very up to date (it came out in May and is set in 2026, leading up to the midterms). He's as funny and acerbic as ever, and it's even fairly upbeat at the end.
(Twilly Spree is a slightly annoying overly effective protagonist and in that he's a worthy successor to Clinton Tyree, who at least was never the protagonist, more that GMPC who comes and saves the PCs when they get in over their heads.)
