Silent to the bone

It is easy to pinpoint the minute when my friend Branwell began his silence. It was there - or, I guess you could say, not there - on the emergency services. Branwell's baby sister, Nikki, lies in a coma. Vivian, the au pair, blames Branwell, and he is placed in a juvenile detention centre. Though Connor is sure his friend would never hurt Nikki - or anyone - how can he get Branwell to communicate? And what does Morris, Vivian's pizza - delivery boyfriend, really know? (From backcover).
