Star Portal

She knew the risk. She went anyway.
Hidden in a crevice of Emma's newly inherited ranch lies a portal to other worlds.
Brimming with curiosity and accompanied by her tough, good-looking, ex-military neighbor, Emma enters the unknown worlds her late uncle had so meticulously tried to hide.
Problem is, exploring is one thing. Returning alive is another thing entirely that requires unraveling the mystery of the portal that binds these worlds together. But how can you do that when you're fighting for your life?
The knowledge and wealth of a thousand worlds is the reward for braving the dangers of those other worlds but they hold more hideous monsters than she can count and violence is the norm.
Did she make a mistake when she stepped through the portal? And in such dire circumstances, can she trust a man she barely knows?
