Self-promo scheme #1:
Acquire a giant pinata and fill it with copies of your book.
Exchange your book-filled pinata for someone’s candy-filled pinata.
When they beat the pinata to death at their party and/or gathering, copies of your book will come flying out! Everyone will gasp in amazement, since free books are better than free candy, and immediately start reading. The host of the party will be upset that their guests are reading instead of partying, but they will be so entranced by your book that they will forget all about being upset and have a good time.
