A Favorite from Tommy’s creative repertoire, The Mark Twain Book Test is absolutely fabulous! Originally was 3 books but only 2 are still available The Adventures of Huckleberry Finn and The autobiography of Mark Twain. Both book are gaffed in various ways to make the mind reading go that much easier so you can concentrate on your performance. Long words, flashback principle, built in page forces, and some other small goodies. Comes with pdf instruction download. there will be 4 books in total coming soon!
