WIN $500 — The Blackthorne Shelf Challenge

The Blackthorne Shelf Challenge

Win $500 — drawn January 10th.

The Blackthorne Dynasty was written to be binged and displayed. So we're paying tribute to the shelves.

How to enter

  1. Complete your set of all three Blackthorne Dynasty books in physical form — The Vow, The Heir, The Crown. Signed editions from this store, paperbacks or hardcovers from Amazon — any physical copies count.
  2. Take a photo of you with all three books.
  3. Post it publicly on Instagram, Facebook, or TikTok, tag @tiernancrow, and use #BlackthorneShelf.
  4. Send your order number(s) — from this store or Amazon — with a link to your post via the contact form (subject "SHELF CHALLENGE") or by DM to @tiernancrow. Your name goes in the January 10th draw.

Running the other dynasty?

The Heirs Shelf Challenge runs alongside this one — all five Heirs of the Black Dynasty novels, #HeirsShelf, its own $500, its own winner. Enter both.
