When buying a book

I will randomly buy a book, but only after reading a little up on what it's about, and if it's part of a series, if I can get the other books in the series. Sometime the other books in the series aren't readily available, like most of the books in F. Paul Wilson's The Adversary Cycle, only The Keep and The Tomb are readily available (unless you want to spend up to 70.00 for special editions for each title) the final four can be got through used book stores and stuff, but that's not always an easy thing.

If I like a book from a author I just "found" then I will get all the books by them I can, like Jack Ketchum after reading Off Season, or in rare occassions, just buy all I can at once and hope for the best, like F. Paul Wilson's Repairman Jack series, and Robert R. McCammon, who I at one time bought all his books that were in print.

Jam it back in, in the dark.
