I don't know about your students', but mine love it when I do booktalks for them! And, I love doing booktalks! It is a great way to motivate them to read books they otherwise may have never picked up. So, I have set up a website with links to my favorite booktalking sites. I hope you will find them as useful as I do---they are great for getting ideas, motivation, or "borrowing" (giving credit, of course) when you don't have time to write your own booktalk.
