Im sure if you go to your local game shop they would be happy to order the Lone Wolf Books for you.
I have been blessed by a comic shop (shamelessly plugging Olympic Cards and Comics in Lacey, WA, USA) that caters to *everyone*.
-1/2 the store is dedicated to Anime/Manga, DC/Marvel, Statues/Action Figures and items of those gamut. (I could split it further, but I dont frequent this side much.
-1/4 of the store has Wargaming supplies, Mostly Warhammer and Warma/Hordes, but also a good smatering of other peuter mini's
-1/4 of the store has RPGs from the popular Pathfinder and DnD4e to esoteric rpg systems. Name it, 90% sure they got a copy of it, but you may have to dig for the older stuff.
-There's even a wall from floor to ceiling on both sides that are boardgames of all stripes. I'd love to play a game of Dominion or Dust, but I dont know enough friends that like boardgames to justify the purchases
And the cool thing about these owners are that if they *dont* have it, they will look for what you want and order it.
Wow that was a tangent, but the point is, I was able to order many volumes of the Lone Wolf CYOA books.
