Santorini felt like an island holding its breath. As if it were keeping in a secret...

Liv Varanakis doesn’t like to think about her father much, which makes sense—he fled to Greece when she was only eight, leaving her with just a few painful memories of their shared love for the lost city of Atlantis. So when teenage Liv suddenly receives a postcard from her father, who explains that National Geographic is supporting a documentary about his theories on Atlantis—and asks if she will fly out to Greece and help—Liv is less than thrilled.

When she arrives in gorgeous Santorini, things are just as awkward as she'd imagined. There are so many questions, so many emotions that flood to the surface after seeing her father for the first time in years. Liv doesn’t want to get sucked back into her father's world. She also definitely doesn’t want Theo, her father’s charismatic so-called protégé, to witness her struggle.

Even so, she can't help but be charmed by everything Santorini has to offer—the beautiful sunsets, the turquoise water, the sun-drenched villages, and the delicious cuisine. But not everything on the Greek island is as perfect as it seems. Because as Liv slowly begins to discover, her father may not have invited her to Greece for Atlantis, but for something much more important.
