The Vori's Mate: A Mate Index Alien Romance (The Mate Index Book 5) (English Edition)
Reggie was a society girl, a castoff wife, soon to-be divorcee, stolen away from Earth, a victim of her own bad choices. Little did she know that one mistake would lead her onto a journey of finding her own happy ever after with a serpentine species of aliens on a strange matriarchal jungle planet. Giant spiders, gargantuan lizards, scrambled green eggs for breakfast. Life had suddenly got a lot more interesting.

Vadal and Shaagra are from a society where the females choose and dominate, where due to a genetic malady they succumbed to fits of temper and collected males into vast harems. Vadal and Shaagra want more than that. When the opportunity comes to secure a human mate to love and shelter among them, they will risk everything, even their hearts, in hopes that she will be forever theirs.

Warning: this book contains some slight M/M interaction in their bonding with Reggie.
