Perilous by Elle Thorne

Marco Brazos, the only male sibling of a quartet of shifter elementals has a problem. Actually, make that two.
His first problem, the elemental that resides within him has gone silent. Total and complete silence.
Second problem? A beautiful witch named Symone who lives on an island that’s off the grid. She’s not just any witch. She’s the witch that runs the southern hemisphere Circle of Witches.
She has no use for shifters but tolerates them. As for elementals, she hates them, with a passion—for good reason.
Marco’s on her island courtesy of an invitation from her brothers, Jenner and Cedric. He just wants to chill and get in touch with his elemental. He doesn’t need the drama that Symone’s cousin Brigitte brings. He doesn’t need to save an entire community of people. These are not Marco’s problems.
Except, they are. Wish Marco some luck. This gorgeous hunk of an elemental shifter’s going to need all the help he can get.
