Siren's Storm by Asa Maria Bradley

The Sea King sent her and her sisters to earth to prepare for the return of the merfolk. They must do so without other paranormal creatures finding out who they really are, or they will once again be hunted for their ability to create portals between the realms. Theia is doing a pretty good job of staying under the radar, until a wolf shifter arrives in town who won’t rest until he ferrets out who and what she really is.

As if that wasn't enough, strange magic is messing with the fish stock in Lake Pend Oreille. The timing couldn't be worse, because Theia has enough on her hands with the wolf shifter, while also helping one of her sisters hide a powerful magical weapon. And when it is clear that someone is willing to kill her to get to the powerful tool, she is in the fight of her life to stop it from ending up in the hands of the wrong people.

Her failure could mean the end of not just her people, but the start of a massive war that would threaten all creatures that make earth their home.

“Packed with everything it needs to make an exciting story. Pick up this book, you won't be disappointed!” ~Amazon Reviewer
