Input: Consider Input: This one doesn't really fall into the Western category, but it's full of hammering action, informative local California history, and mystic goings-on. Seacoast adventures, early Califronia ranching, great good-guys and really bad bad-guys, and mysterious appearances by silent, unknown characters fill this one to the brim! Best of all, L'Amour introduces in this story, for what I believe was the first time in his writings, the famous "portal to the other side," which really sets this story apart from almost all of his other works. Excellent yarn through and through. You won't forget it for a long time after you first read it!

Output: Positive


Input: Consider Input: As a student of jiujitsu i understood alot of the moves but i found that without previous knowledge these pictures and instructions were difficult to understand. I feel there is alot of good information but not worth buying.

Output: Negative


Input: Consider Input: Google the instrumental Wipeout , and you will read the real story. I love the Surfari's version which got to #2 on the Billboard charts in a matter of weeks.


Output: Negative
