Hot SEAL, Australian Nights by Becca Jameson

Ten days… No strings attached… The perfect vacation…
He’s a SEAL married to the team.
She’s his teammate’s little sister, all grown up.
He’s on the vacation of a lifetime.
She’s playing tour guide.
He’s everything she remembers and way more.
She’s no longer a gangly teenager.
He doesn’t ever want to get attached to a woman.
She doesn’t date military men.
How can they hook up and then walk away?
How can they not?
Everything about this no-strings-attached arrangement should be easy.
Except the part where they have to guard their hearts.
