Dream Weaver by Olin Powers
Franks Evans, New York City orphan, US Marine, CIA Operative, Bangkok drunk, and philanderer, finds himself at a crossroad of life and death.
Johnny Gould, disheartened California dreamer, hard on with a heart, and hopeless romantic, is hurled into a steaming, soul-searching, sexual adventure of a lifetime.
Harry Doughty, happy-go-lucky incorrigible rascal, chases the elusive American Dream, only to find himself spending his Golden Years pondering a blind jump into improbable romance.
Ansel Bean, privileged nerd, misanthrope, and hapless underdog, attempts to break out of his dull life in London to delve unwittingly into a whirlwind of flesh and mayhem.
Collect the above, add a sundry of stunning Asian temptresses, barons of industry, and intractable washouts, place in a wok, spice heavily with raw libido, fantasy, greed and compassion, stir over open flame and simmer until the reader is served a feast of erotic adventure, delight, passion, illusion, tragedy and ruin.
