At only twenty, Tara Tremain has everything: she’s a trainee doctor, engaged to the man of her dreams – Alex, a passionate American biology student. But just when life seems perfect, Alex betrays her in the worst way possible.

But when she’s pulled back into her wealthy family’s orbit for a party in the heart of Costa Rica, she’s flung into a crisis: a child is desperately ill and the only treatment is several days’ trek away, deep in the jungle.

There’s only one person who can help – but can she trust the man who broke her heart?
