I am not a collector, but I put together complete series from all of my trading sites and when I get one complete I list it here, I am pretty famous on Listia fro my V. C. Andrews auctions, and have at least 10 people who have completed their collections from my auctions her, I will be listing the Shadow series this afternoon.
Books completed by V.C. Andrews are; "Flowers in the Attic," "Petals on the Wind," "If There Be Thorns," "My Sweet Audrina," "Heaven" and "Dark Angel." "Seeds of Yesterday" and "Garden of Shadows" were partially written by Andrews before her death and finished by ghostwriter Andrew Neiderman. Subsequent books (more than fifty titles) published under the V.C. Andrews name were written by Neiderman.
