Prenna James is a Traveler. She doesn't belong in the 21st Century. She isn't supposed to be enjoying the fresh air, gentle rain, and safe outdoors. She is from the future where people are afraid to go outdoors due to a mosquito-borne illness that has mutated into a pandemic, killing millions and leaving the world in ruins.
She and all the other Travelers live by a very strict set of rules that are heavily enforced. Prenna knows not to disturb the natural order of events; knows not to talk about where she is from; knows not to talk about what will happen - and especially, she knows not to form intimate attachments to time natives.
Ethan Jarves, a boy she goes to school with, doesn't make following the rules very easy. He has a way of looking at her that makes her want to tell him everything. Makes her think he already knows her secrets. But, for her safety and his, she keeps quiet - until someone from her time reveals a terrible secret about the leaders of the Travelers and she is forced to take action.
Together, Prenna and Ethan attempt to save the world. But, what if saving the world means they can never be together?
AMAZING!!! That is truly what this book is. I loved Prenna and Ethan. And, man, the tension that Ann Brashares writes in some of the scenes is palpable. THE HERE AND NOW is nothing at all like the SISTERHOOD so don't let that series sway you one way or the other on this book. So, if you didn't like SISTERHOOD, give this a try. If you loved SISTERHOOD, give this a try, but be aware it's a different kind of book.
