Very YA. Very good twist.
Maddie is allergic to the world and never leaves her house. The only people she can see are her mum and her nurse, Carla.
That is until the new neighbours move in and she sees Olly. Tall, dark and staring up at her. They begin talking through the window and signs, until one day they finally meet.
This book makes you think and feel many things. I felt engaged throughout. It included many memorable quotes, short chapters and was a great YA read.
