Query: Overall, thorough but dense book

I used this for high school freshman introductory biology, and boy! The writing is dense and excessively formal, and some concepts weren't explained very well. It's a gorgeous book, though, with beautiful color photos and computer diagrams, and it's chock-full of bios and anecdotes. Buy it was a coffee-table book, not as a simple biology text for regular high school kids. (The test questions, which my teacher used from the cd test bank, were devastating. You wouldn't believe the nitpicky details they asked you)
