-J.B. Bobo's Modern Coin Magic
-Mark Wilson's Complete Course in Magic
completely agree besides bobos...i for some reason dislike it.
Mark Wilsons books are amazing...There cheap and give a TON OF TRICKS. I got that book when i was i beleive 5 years old (awhile ago). Its not the SAME EXACT one, but identical. This book i got at a book store marked down for 4 bucks. i bought it, and releized these tricks were difficult. Now with more experience i look at the book and releize how golden that book it. It gives FULL routines of every type of magic. It teaches you forces, self working tricks, ect. Although the arent the HIGHEST and most shocker of effects, it teaches you stuff if you sitting at a table with friends and that want to see something quick. After re-reading the book, and forces, i made my own version of paperclipper (the ending card does not appeared signed) However, my version is basically no sleight of hand, and everything is inspectable and in plain view. I learned that off basic ideas taught in this book. I love it, i cant stress it enough to buy it.
Sponge balls is also great, and in my wilson book, he gives a good routine for you to do. The book is very visual took, theres pics for every step.
