I can't really do more than echo the praises of other reviewers, but I wanted to add that this excellent book will be also be indispensible for many parents of children with autism, Asperger's syndrome or PDD-NOS. Most of the examples in the book focus on kids with ADHD or Tourette's, and the book only mentions PDD very briefly, but its wise advice would be equally relevant to verbal kids with autistic spectrum conditions who have rage attacks/tantrums, as many do.
I'm speaking from personal experience here - I have Asperger's syndrome (a mild autistic spectrum condition), and, looking back, as a child I definitely fitted the "inflexible-explosive" patterns described in the book. This book encapsulates all the wisdom my exhausted parents had to learn the hard way.
I already know of at least one parent of a teenager with AS who is currently finding the book absolutely lifesaving, and I've had to buy several copies to lend to people.
It's thoughtful, humane, and very practical. Very highly recommended.
