Local Libraries: Check your local public libraries. Many libraries have a substantial collection of books and short story anthologies, including potentially "The Girl Who Cried Flowers and Other Tales."
Interlibrary Loan: If your local library doesn't have a copy, you can try requesting the book through interlibrary loan. This service allows libraries to borrow books from other libraries, so you may be able to get a copy of the collection this way.
Online Bookstores: Look for secondhand booksellers or specialized online bookstores that may have the "Girl Who Cried Flowers and Other Tales" collection in stock. Websites like Amazon, Barnes & Noble, or Abebooks may have used copies available.
Jane Yolen's Website: Jane Yolen is an acclaimed author with an active online presence. It's possible she has information or resources on her website related to "Suzy and Leah" and where it can be found.
Contacting the Publisher: Try reaching out to the publisher of the book, HarperCollins, to inquire if they have any remaining copies or know of any sources for obtaining it.
Online Archives and Databases: Some libraries or digital archives may have digitized versions of the collection or short story. Check platforms like Project Gutenberg, Internet Archive, or other online databases for potential access.
