I recall these characters - the book was futuristic, high-tech - set in Eastern US - languages included Black Spanglish - Guig is a member of a group who has become immortal by narrowly averting death - Fee is his adopted waif housekeeper/daughter figure - Dr. Sequoia Guest is Guig's latest candidate to turn into a fellow immortal - Guig then meets Sequoia's family near the Lake Erie reservation where poisoned poppies are grown to sell - accidentally marries Sequoia's sister Natoma - other members of the immortals group are being wiped out - bad things happen - Guig loses his reailty and becomes an alternate character, Capo Rip, for a time - other characters include a caveman, a girl with an elephant, and a Rajah. Can't recall the title or the author - really would like to find it again. Thanks!
