Woman with male harem/reverse harem
 
Swept up in the government plan to transport the poor to a new colony world, Mariah gets booted for health reasons before the ship sails and has to scramble to find a way to accompany her daughter and infant granddaughters. Tristan is the Herc she buys to protect them on the primitive world, but nothing goes quite according to plan.

Or actually, at all.

Tristan imprints on her as his mistress and Hayden and Dakota aren't just hard to discourage. They're impossible. And she isn't as immune as she wishes she was.
