I have recently been on holidays and read a chapter in this young adult book and now I can't remember what it's called. I also read it in German which means finding it in English is even harder.
There is a young boy, who works in the guard (I think) in this magical land , and he is a stable boy or something. He is chosen by a bird of prey - not sure what it is called. I think the magical land is in the middle of war because of a drought.
There is a girl in the "real world", and she drives her scooter or bicycle through a storm home and I think she gets a talisman from her Irish grandmother as a present.
This is all I have - I think the title was something like "the prophetess of the rain".
I have searched high and low for this book and even tried to contact the hotel but no one could help :(
