Castaways by Lily Harlem

Olivia Bailey is up for The Challenge. Why the heck wouldn’t she be? With mariner qualifications piled high, engineering experience to rival someone twice her age, she’s ready to take on the mighty Pacific Ocean and win.
But what about her fellow crew? Five guys, four nationalities. A billionaire’s heir who likes to take charge in every aspect of life, an outback expert with a heart-stopping smile, a Spanish chef with mouthwatering moves and sexy twins who reveal themselves slowly, until it matters, then they act fast.
An adventure was what Olivia wanted, it’s certainly what she gets. Because things at sea happen in a heartbeat, friendships grow, tempers heat and desire flares. But what about when it all upends? When the unexpected happens? Will they pull together, or will fear drag the crew of The Temptress apart?
