Saxon by Annalise Alexis

She knew the ocean had hidden depths, but she never expected to find him.

Leigh always wanted to be something—wanted to accomplish what her disgraced scientist father never could. Being the first female to design and captain an underwater craft capable of reaching the lowest point on Earth was a dream come true…
Until it turned into a nightmare.
Saxon left his home planet of Revaris in search of his mate. But when his travel pod malfunctions, he’s trapped in slumber in a place so isolated, there’s no one to save him from his induced sleep.
Until her panicked call woke him.
He rescued her from the treacherous depths, but now that they’re both on land, their battle for survival is only beginning.
Someone’s determined to have them both, and they’re willing to do anything to keep them. Dead or alive.
