Hannah Bell, the oldest of the three Bell sisters, spends most of her time in the remotest parts of the world photographing endangered animals. She is also gifted with an extraordinary sixth sense, which has saved her life on more than one occasion.

What she doesn't know is her sister's best friend's new science experiment has opened a portal to another world - a world she is about to be taken to whether she wants to go or not.

Borj 'Tag Krell Manok is the calmest of his four brothers, or so he always thought. The second oldest, he has been assigned the task by his father and the council to bring the sister of his brother's bond mate to their world. Borj knows deep down that Hannah is destined to be his bond mate - something he has hoped for since his first mating-rite ceremony. What he doesn't expect when he meets her is her resistance - or her independence.

When she is kidnapped by a rival clan, Borj will do anything to get her back. Hannah and Borj's escape into the vast forests of Prime draw them together in a fight not only for their lives but for a deeper understanding and trust between two vastly different worlds. Borj discovers Hannah is a fierce and cunning mate while Hannah discovers Borj is the perfect warrior to protect and love her.
