Query: Painful reading/ Better book recommended

This book was truly painful reading! Possibly the worst book I've ever read. I slogged through it because a friend told me I just had to read it (I've been wondering about her ever since).Instead of reading this really bad book, I recommend reading Tom Robbins' "Fierce Invalids Home From Hot Climates", which is a well-written, fun-to-read, actual adventure story that develops similar ideas.
