Second Hearts, book 2 of The Wishes Series.

Charli Blake's high tolerance for risk doesn't always work in her favour.
After a year of living out her dream of travelling the world, the sunny West African village of Kaimte would be her last stop.
She's bound for New York, in search of the boy she'd let go of long ago.
For Charli, nothing has changed. She's travelled thousands of miles but hasn't moved an inch. Adam Décarie still means everything to her.
But reality soon hits hard.
For Adam, everything has changed.
Memories of the best love she's ever known is all she has left, until Charli makes a shocking discovery. None of it had ever been real in the first place.
