This book was written well, but I feel like this plot is overdone. This group of people send a video to this Hannah who is all about natural things and making yourself better. She invites a number of them to her place in Costa Rica for a retreat. But when they all get there, she is stuck somewhere else. 90% of this book takes places in the rainforest. What happened there was very predictable. If you haven’t read a book with this setting before, you will probably love this book. But I have read tons with this same storyline and they all seem to follow the same basic outline, so too predictable for me.
