Love in Australia by Emily Silver

A year living abroad in Australia? The land of Hemsworths, kangaroos and vegemite? It’s going to be a good year. Until the unexpected happens.
Reagan is ready to have the year of her life in Sydney. Men, adventure, she wants it all. Her first week in the city, she meets a fiery stranger who rocks her world.
When two blue lines appear on that stick, Reagan’s year of adventure is turned on its head. In a country where she knows no one, she now must rely on her sexy stranger for help.
And that mystery stranger? Turns out, he’s her boss.
The last thing Leo needed was his one-night stand coming into the office. Even worse? When she tells him she’s pregnant. The spitfire of a woman drives him crazy. He doesn’t want to be attracted to her, but he can’t help it.
Things just got a whole lot more complicated Down Under.
