"Brilliant, fascinating and deeply moving ... gracefully written, this is a book that astonishes, even as it shows the way to cross divides ... Full of science, love and drama, I couldn't love this book more if I tried." - Caroline Leavitt, New York Times bestselling author of With or Without You

​

"An emotional read full of page-turning highs and cathartic sorrows. I fell in love with this complicated, compelling cast, both human and otherwise." -Katrina Kittle, author of Morning In This Broken World
