Book excerpt: "Schizophrenia. Helicopter Man first demonstrated this, and Goodbye Jamie Boyd continues to do so, and whether mental illness inspires Fensham in some way because of the inherent internal conflict to be found there, or whether her research for Helicopter Man has prompted her to explore the theme for older readers is beside the point. The fact is that she does it very well, particularly in the way she keeps the reader somewhat in the dark for the first third or more of the book, keeping Jamies identity something of a mystery. As I read, I wondered in turn whether Jamie was (in no particular order): real; or an imaginary friend; or a ghost; or a manifestation of mental illness. And with every exchange between Anna and Jamie during the first part of the book, each of these possibilities provides its own sinister implications (although the scene on the bus is a bit of a loose clue). But as far as I can tell, this uncertainty about what is reality and what isn't is a very real part of the struggle with schizophrenia."--Provided by publisher.
