Loved how this book flowed, it made sense and even though there were multiple perspectives it was clearly labeled who was talking (and whether it was past or present) but the sections also sounded like slightly different voices. 
The sections with the physiatrist were the ones that threw me but they were supposed to! It also helped pull the story along and keep focus on the main story while all the little side stories happen. The ending had me Floored, Oh My God.
