Other: I picked a book out of my cousin's bookshelf on a visit to her home when I was maybe 9. Now own most of Georgette Heyer's books in paperback, many in hardcover, and working on an ebook collection.
Another favorite, Dick Francis, I knew about from working in a bookstore, but would never have read had I not discovered my grandmother reading his books. So I borrowed from the library and became hooked.

I have a full set in paperback (older titles), hardcover (newer or favorite titles), and ebooks (newest, including books co-written by Felix Francis).
A magazine review and prompting from my husband brought 2 current favorites my way. Another old favorite I discovered in a Reader's Digest Condensed Book while waiting to be served in a crowded restaurant.
Libraries, I love libraries (especially for ebooks)!!
