I love this book. It's the third I'm attempting after my concussion and, while I'm only a fifth of the way through, I really like how it's added depth and breadth to my understanding and my recovery.
Of note, though: I'm only a fifth of the way through because, despite being an avid reader before the concussion, the font is just too small and the pages have too little white space for this to be an easy/comfortable read for any real length of time post-TBI.
Same book in a slightly larger font with slightly more white space? Perfect. Not a place to start your recovery, but definitely a good/important place to go (for starters, I recommend the Brain Injury Survival Kit and then The Mild Traumatic Brain Injury Workbook).
