I picked up "The Islands of Purple Haunted Putrescence" by Venger As'Nas Satanis on PDF couple weeks ago. In my opinions it's kinda like 'Lost' meets 'Land of the Lost' (both 1974 and movie version) with various other Fantasy and Sci-Fi mixed in, with a good dose of Lovecraftian flavor added. So like in 'Lost' instead of the island pulling down airliners, it pulls in star ships and dimension portals in people/things from across time/space/dimensions.
Loved this so much, I ordered a print copy as well as the 'Liberation of the Demon Slayer', also by same author.
If you love crazy gonzo settings, definitely give it a look!
