Wild Fire by Christine Feehan
The air around her suddenly changed, charging, pressure pushing on her chest. She turned, still reaching for her tank, when she felt the tremendous swell building beneath her. Rikki turned her head and her breath caught in her throat. Her heart slammed against her chest as she stared at the solid wall of water rising up out of the sea like a monstrous tsunami, a wave beyond anything she'd ever witnessed.
