I would say buy the book, before you buy the cigar. Basically, do a little research to get an idea of the most popular tobaccos, by country. Perhaps a good predominantly Dominican tobacco cigar, a Nice Nicaraguan Puro, and a Honduran Cigar. Maybe same tobaccos with Cameroon wrappers.
Get a feel for what Ligero is and if you like cigars loaded with it, or those who use enough to give the cigar a little oomph. Stay away from so called bargains containing a pile of second or third tier cigars.
Either way you go, have fun first, and learn to smoke slowly, and meditatively. Relaxing and savoring the cigar.
Welcome aboard.
