Blurb:
All Maelan wants is to do his duty to his Chief and maintain his family’s good name. His granddaughter Orlagh, however, is hell bent on ruining everything. After the Fae get involved, he is backed into a corner. In the end, he may have to choose between her happiness and her life.
Taglines:
Could you choose between life and happiness?
Maelan must make some difficult decisions to save his granddaughter’s life, but can he save her happiness as well?
Hmm. I like the second tagline, but the first needs... something. Not sure what - perhaps words that stress that you're making the choice for someone else.
For the blurb, consider the following:
Maelan just wants to do his duty to his Chief and maintain his family’s good name. Orlagh, meanwhile, seems hell-bent on ruining everything, and once the Fae get involved... He may have to choose between his granddaughter's happiness and her life.
