House of Gods 2: The Baby by Amira Rain

Falling in love with four demigods is the least of her worries now that she’s pregnant with a powerful child wanted by the gods.
Brenna Evans never imagined this was how her life would turn out.
Pregnant and on the run from hunters wanting to kill her unborn child, Brenna accepts the protection of the demigod Brandt Ridley and his three friends, any of whom could be the father of her child.
As Brenna struggles to make the difficult choice of selecting a mate from the four men, the prophecy surrounding her child changes, throwing her life into further chaos. The Goddess Freya and the God Lopt become locked in a battle to claim Brenna and her gifted baby, complicating things for Brenna and the decision she must make.
But that’s not all. As the baby grows, the stronger it becomes, and now its destructive powers have transferred to Brenna who must learn to control her new abilities before they consume her.
