A Brother's Price
I couldn’t resist Wen Spencer’s latest:
On an alternate Earth, where the population is ninety percent female and a man is sold by his sisters to marry all the women in a family, Jerin Whistler is coming of age. His mothers are respected landed gentry, his grandfather a kidnapped prince, and his grandmothers common line soldiers blackballed for treason, trained by thieves, re-enlisted as spies, and knighted for acts of valor. Jerin wants to marry well, and his sisters want a husband bought by his brother’s price.
