Recently, I have acquired a nasty stomach bug, and I have been struggling. During my struggles, I have purchased some new books, and one of the new books was the Sloane Ranger Handbook. It is a good read, and heavily influenced by the OPHB (which I think came out before). Honestly, I may have found it more fascinating than the OPHB. Pick up a copy soon (they are cheap) because once someone makes a big deal about it, it will certainly rise in price.
