I started this series probably 15 years ago, maybe more. I remember being so wrapped up in this interactive adventure that I couldn't wait to get my hands on the next installment. Well, while cleaning off my shelves a few days ago I stumbled across these gems and I tell you, I got overwhelmed with the same feelings.
You are Lone Wolf, the last of the Kai Warriors in the land of Sommerlund. Throughout your adventures (the are 28 books and 4 "World of Lone Wolf" books) you will face monsters big and small, wizards, magicians, puzzles, riddles, and everything else your imagination can think of.
This book is just like your standard "Choose Your Own Adventure" book except that it is more interactive. Not only do you choose your path, but you also choose your skills, equipment, and whether or not you want to battle enemies. This book employs an interesting combat system in which you pick a number from the "Random Number Table" at the end of the book by closing your eyes and poking the page with your eraser. I highly recommend getting ahold of a 10-sided die to use instead, because after a few books one can learn where the higher number areas are.
"Castle Death" is a rather disappointing addition to the series. This book is unoriginal. It is your basic dungeon crawl on a quest that feels like it could have been left out of the overarching series. Additionally, the title, "Castle Death," is incredibly uninspired and unoriginal. However, it is still a fun adventure and necessary to play if you are going through the series. Just don't expect too much in terms of plot and setting development.
I had the first 15 books of the series when I was younger and now that I've reread them, I am scrounging ebay and used Amazon books to locate the next ones. Unfortunately all of these books are out of print. If you are looking for these books, I highly recommend getting the UK editions of books 12-20 because the US editions are abridged and are missing huge sections. Additionally, there are many "broken links" since they were edited so when it says to turn to page XX it takes you to the wrong place. Also, good luck finding books 21-28 as they were ONLY printed in the UK. They are very rare and if you have them, hold on to them!
Finally, Joe Dever has authorized the free distribution and licensing of his Lone Wolf series which are available online. This resource has the unabridged editions which makes it great. I will not give out the URL as part of the reviewers agreement but with a little searching you should be able to find it. However, I still prefer to read the paperback versions instead of an online version.
