Yes, there is romance, love and some sex (very tame, but clearly sex). And there is a little sci-fi stuff with mind reading and telepathy.
But there is so much more...we have war and peace, friendship, belonging, courage and danger. We have a young girl - lost, angry, anorexic - who doesn't know who she is anymore, coming to England for the summer to stay with her cousins. But war breaks out and Daisy suddenly has to step up, get involved and take care of herself and her cousins.
It's beautifully written and engaging. I went along for the ride and loved it.
